Built Around Your Licence Stipulations · Staff Can’t Pass the Caps · Quiet for the Flat Upstairs · Brooklyn Price List
Williamsburg plays music for a living. ZIP 11211 holds 286 active restaurant and food-and-beverage liquor licences, more than any other ZIP in Brooklyn, and almost four in ten homes across 11211 and 11249 sit in buildings that also hold a business. So most Sonos systems we install here are on one side of a floor that has a bar, a café or a shop on the other. For the business, we build the system around what the licence and the community board allow, put the controls in the right hands and use licensed music. For the home above, we keep your own system considerate and help you ask the right things of the room downstairs. Every price is on our Brooklyn list.

Two things decide a Williamsburg Sonos job before we see a speaker: what your licence or lease says about sound, and who lives on the other side of your ceiling or floor. A photo of the stipulation page, or of the ceiling, usually tells us both. Call (347) 934-8335 or use the form; it takes about a minute.
Williamsburg has been making noise in industrial buildings for a long time, and it has been arguing about it for nearly as long. Wikipedia’s history of the neighbourhood describes how, from the late 1980s through the 1990s, unlicensed performance and music venues ran in abandoned industrial buildings, and one 1993 event at the Old Dutch Mustard Factory drew more than 2,000 people. By the early 2000s the neighbourhood was a centre of indie rock and electroclash, and soul and funk labels such as Daptone grew up here. The warehouses became lofts, the lofts filled with residents, and the clubs that remained became licensed bars, restaurants and venues with neighbours above them.
That last part is the one that shapes our work. Wikipedia’s land-use summary describes North Williamsburg as light industrial and medium-density residential buildings, “as well as some residential structures with commercial space on the ground floors,” high-density residential developments with commercial space along the waterfront, Broadway as mainly stores and offices, and South Williamsburg as largely medium-to-high density residential “with some commercial space on the ground floors.” We checked that against the city’s own lot records. In the city’s PLUTO data for ZIPs 11211 and 11249, 1,675 lots are classed as mixed residential and commercial buildings, and they hold 20,098 of the area’s 51,973 homes. Across Brooklyn the same category holds about one home in five; here it is close to two in five.
The businesses are just as dense. The State Liquor Authority’s open list of active licences shows 286 restaurant and food-and-beverage licences in ZIP 11211 alone, the most of any Brooklyn ZIP, plus 107 in the riverfront ZIP 11249. The Postal Service split 11211 in 2011, citing, in Wikipedia’s account, a large increase in population “and in the number of companies doing business in our area.” Add the 60 additional-bar licences, ten hotel licences and two cabarets across the two ZIPs and you have a neighbourhood where background music is part of the business plan on most commercial blocks.
The friction is on the public record. In April 2011 the Brooklyn Paper reported Community Board 1’s chairman proposing a moratorium on new liquor licences, saying the district had “reached its breaking point” and was “oversaturated” with venues that brought, among other things, “loud music.” The board’s own liquor licence questionnaire now asks applicants whether they will keep openable fronts closed while amplified music plays, whether they will follow a certified sound engineer’s recommendations “including placing speakers on the floor,” and, for outdoor space, it states “No speakers or live music in backyard. No background music.” In 2023 Greenpointers reported residents next to a hotel near McCarren Park telling the board about bass from a rooftop lounge and a basement club; the city’s Department of Environmental Protection had issued a summons for commercial music over the allowable limits.
So this page is about both sides of the floor. For a business, a good Sonos system in Williamsburg is one designed around what the licence and the board will allow, with speakers placed and capped so the room sounds full without the flat upstairs hearing the bass, staff who can run it without being able to break it, and music the business is licensed to play. For a home above a business, it is a system that is considerate in its own right, plus a clear idea of what to ask of the room downstairs. Most of the tools are already in the Sonos app and the Sonos Pro dashboard. They just need to be set by someone who has read the stipulations.
A Sonos job here often grows by one item. If the TV over the bar is being rehung anyway, the TV installation team for Williamsburg can do it on the same visit; if the speakers keep dropping because the back room has no wired network, a run from Williamsburg structured cabling usually ends it. Both are priced from the same Brooklyn list.

Most calls we get from Williamsburg bars and cafés are not about broken hardware. A new router left the tablet unable to find the speakers, an app update dropped the schedule, or someone regrouped the rooms on a Saturday and nobody can put them back. Phone (347) 934-8335 for the next two-hour arrival window; most are sorted in an hour or two on site, billed on the Brooklyn setup-only line at $195 for the first hour and half-hour blocks after.
These are the nine jobs we are asked for most in Williamsburg. Six of them are for businesses, and three are for homes that share a building with one. Each card names the decision that matters most for that kind of space.
Systems for bars and restaurants approved for recorded background music: many small speakers at low level, no open inputs, caps set below conversation level and written down.
Rooms and zones named, schedules entered for opening hours, remote volume limits, and staff given only the features you choose in the Sonos Pro dashboard.
Network cable and PoE+ switch ports for Sonos’s installer-only speaker, which takes power and data on one cable; we run, test and label every drop.
Stand, wall and isolated mounts for shops and cafés under apartments, matching CB1’s wording about speakers on the floor and keeping vibration out of the joists.
Lobby, restaurant, back bar and roof on one dashboard, each with its own schedule and limit, and outdoor rooms set to the hours the licence allows.
Two to six speakers on Bedford Avenue or Grand Street retail floors, a commercially licensed service, and a schedule that starts and stops with the shutters.
Soundbars, rears and Subs placed off the floor that sits over the shop, Night Sound for late TV, and rooms that never send bass into the stair hall.
Wireless-first systems for post-2005 condos and rentals along Kent Avenue and the river: concrete walls, metal-stud partitions, building Wi-Fi rules.
Freestanding, no-drill systems on a business account that move with the shop to its next address and leave the walls as found.

We wanted to know how much of the neighbourhood’s music is played by businesses before writing a page about it, so we went to the open data. The State Liquor Authority publishes every active licence with its ZIP code and type. Grouping Brooklyn by ZIP and counting the two descriptions that cover most sit-down eating and drinking places, “Restaurant” and “Food & Beverage Business,” gives the ranking below.
Williamsburg leads by a wide margin. ZIP 11211 has 286 of these licences; the next, 11215 around Park Slope, has 200, and Brooklyn Heights and Downtown in 11201 have 197. Add 11249 and the two Williamsburg ZIPs hold 393 of the 2,728 such licences listed in Brooklyn, about one in seven, in a small corner of the borough. Each of those rooms either plays music or chooses not to, and most of them have neighbours.
The licence type tells us something about the system before we visit. A restaurant licence usually means one dining room and a bar. An additional-bar licence means a second bar inside a licensed premises, so a back room, a basement or a roof with its own schedule. A hotel licence often means a lobby, a restaurant and a rooftop under one owner. A temporary retail permit is a pop-up that will move. Each gets a different layout and a different set of permissions.
Busy and mixed at once. Licences are only half the picture; the other half is who lives above them. Putting the licence counts beside the share of homes on mixed-use lots for ten of Brooklyn’s busiest restaurant ZIPs shows why Williamsburg needs its own page.
Close up, the density is even plainer. Every licence application comes with a list of the licensed premises nearby, because the State Liquor Authority weighs how many there are. The list filed with one 2019 application on Grand Street is a fair picture of a Williamsburg commercial block.
Two cautions. 11211 reaches into East Williamsburg, so its count includes some of that area, and South Williamsburg is partly in 11206, which we left out. And a licence is not a music system; some licensed places play nothing at all. We use the figures to understand the neighbourhood, not to point at anyone, and the dataset is public if you want to repeat the query.
Williamsburg’s buildings come from two bursts. PLUTO puts about half of today’s homes in buildings from before 1940, most of them from the decades after the Williamsburg Bridge opened in 1903 and the neighbourhood became, in Wikipedia’s words, the most densely populated in the city. A third are in buildings from 2005 or later. Very little was built in between. Each of the building types below puts a business and a home together in its own way, and that decides how sound gets from one to the other.
The four- and five-storey buildings with a shop on the ground floor that line Grand Street, Metropolitan Avenue, Graham Avenue and much of the South Side. PLUTO counts 1,316 pre-1940 mixed-use lots here holding about 7,500 homes. The floor between shop and flat is usually timber joists under an old tin or plaster ceiling, and it carries bass well.
Inside those walk-ups, long apartments with rooms in a line from street to rear, sitting directly over the business below. A Sub here goes on a rug, off the outside wall and away from the front room that sits over the bar’s speakers, and the soundbar faces down the length of the flat, not into the floor.
Former factories and warehouses where people live under the Loft Law, the 1982 state law the city’s Loft Board administers, which the Board says covers buildings in the Greenpoint and Williamsburg business zones. Ground floors are often still commercial: studios, bars, workshops. Concrete or heavy timber floors, exposed ceilings and long, open rooms.
The waterfront and inland towers that followed the May 2005 rezoning, from Kent Avenue to the Domino site. PLUTO shows 239 mixed-use lots built since 2005 holding 9,573 homes, up to 52 floors. Concrete slabs, metal-stud partitions, a café or gym under the lowest apartments, and building rules on alterations.
Buildings that went from industry to workplaces, the Refinery at Domino among them, which is now offices inside a landmarked brick shell. Kitchens and lounges get music; meeting rooms and phone booths do not. Ceilings are often open, so cable is planned to be seen and tidy.
Medium-to-high density residential buildings of South Williamsburg, many with ground-floor shops on Lee Avenue and Broadway. Families are often large and apartments busy, so we favour simple controls, sleep timers and alarms, and limits that respect the floor below.
| Building | How the business and the home share sound | What we do about it |
|---|---|---|
| Pre-war storefront walk-up | Through a timber floor-ceiling; speakers fixed to the shop ceiling shake the joists of the flat above | Shop speakers on stands or walls, Sub on isolation feet off the party wall, low caps after 10 p.m. |
| Railroad flat above a shop | The whole apartment sits over the business; front rooms are often right over the bar | Home Sub on a rug away from the front, soundbar on a console or wall facing along the flat, Night Sound on |
| Loft Law building | Concrete or heavy timber floors; long reverberant rooms make people turn music up | More speakers at lower level, Trueplay where supported, visible cable in neat raceway |
| Post-2005 tower over retail | Slabs block more mid-range but carry impacts; the café or gym below may be the louder neighbour | Wireless-first home systems, Subs on isolation, building approvals for any cut-in |
| Converted factory offices | Open ceilings and glass partitions let music spread into meeting rooms | Zones that leave quiet rooms out, speakers aimed into kitchens and lounges only |
| South Side apartment buildings | Masonry walls, busy households, shops below on the main streets | Simple room names, sleep timers and alarms, conservative limits on floors over a shop |

On tin and plaster ceilings in old storefronts: many ground-floor shops on the commercial strips still have their original pressed-tin or plaster ceilings on wood joists, with the floor of the apartment above resting on the same joists. A speaker screwed into that ceiling is, for practical purposes, screwed into the neighbour’s floor. It is the reason we read the board’s “speakers on the floor” wording literally in these buildings, and why a cut-in ceiling speaker in an old storefront is a decision for the sound engineer’s report rather than a default.
On new towers: the slabs in post-2005 buildings stop far more airborne sound than a timber floor, so a well-placed home system rarely troubles anyone. What travels is structure-borne energy: a Sub standing on the slab, a speaker fixed to a column. Isolation feet, a rug and placement off the concrete walls do most of the work. Any cut into a ceiling or wall needs the building’s approval first, and we work from the alteration rules the management office gives you.

The single most useful thing we can do for a business with homes above it costs nothing in hardware: deciding where the speakers are fixed. Music reaches an upstairs flat in two ways. Some travels through the air and the gaps in the floor, and the floor stops a fair amount of it. The rest is vibration: a speaker or Sub bolted to the building shakes the structure itself, and the ceiling of the shop is the floor of the flat. The bass in that vibration is what neighbours describe, which is why the complaint in Greenpointers’ 2023 report was “the bass of my head,” and why a reader replying to it wrote that no engineer could guarantee immunity from bass travelling through shared walls.
Community Board 1 asks licence applicants whether they will follow a certified sound engineer’s recommendations “including placing speakers on the floor of the establishment.” Acoustically, that makes sense. A speaker on a stand or a low wall bracket has no direct connection to the upstairs floor, and it is aimed at the people in the room, so the room can sound full at a lower level. A speaker hung from the ceiling is the opposite on both counts: fixed to the joists and aimed down from the furthest point from the listeners. For Sonos, this usually means Era 100 or Five speakers on stands, shelves or wall mounts, or Era 100 Pro on surface mounts on walls, rather than in-ceiling speakers on an Amp.
In a long Williamsburg storefront, two loud speakers by the bar leave the back tables quiet, so the volume goes up until the back is happy and the front is too loud. Six smaller speakers spread down the room do the same job at a lower level each, which means less energy into the structure and more even sound. It is the same reasoning that sits behind Sonos’s zones feature, which treats several speakers as one semi-permanent group controlled like a single speaker. One slider, one cap, many speakers at a sensible level.
A background-music room rarely needs a Sub at all. Where it earns its place, for a dinner room or a bar that wants weight, it goes on isolation feet, off the party wall and off any slab shared with a home, with Sub level set by ear at the busiest hour and the cap set after that. When a hotel owner told Greenpointers he had asked his managers to turn down the bass, he was describing the right lever. We make sure that lever is set once, by the owner, and is not a slider any member of staff can push back up.

Williamsburg’s commercial streets each have their own kind of room. In all of them, the system we install is shaped by three documents more than by taste: the liquor licence and its method of operation, any community agreement signed with Community Board 1, and the music licence that lets the business play songs in public at all.
The North Side’s main shopping street, around the L train’s Bedford Avenue station, where large chain stores arrived in 2016 alongside independent shops, cafés and bars. Retail floors want music customers barely notice; cafés want it to change through the day.
One of Williamsburg’s two major commercial strips and the line between North Side and South Side, with its own business improvement district. Restaurants and bars in pre-war walk-ups, flats above, and dozens of licensed premises within a short walk of each other.
The other main commercial strip, with bars, restaurants and shops in mixed-use buildings toward the BQE and beyond. Many rooms are long and narrow with a back area, which suits zones and a lower evening cap.
The waterfront corridor of hotels, music venues and post-2005 towers with retail bases: Brooklyn Bowl at 61 Wythe Avenue, hotel rooftops above, and restaurants at the foot of new residential buildings.
Stores and offices under the J, M and Z trains, plus venues such as Baby’s All Right at 146 Broadway and the event space in the landmarked Williamsburgh Savings Bank at 175 Broadway. Train noise outside tempts rooms to play louder; caps stop that creeping up.
Graham Avenue, the “Avenue of Puerto Rico”; Lee Avenue, the commercial spine of South Williamsburg; and the Moore Street Market, opened in 1941. Small shops with homes above, where a quiet, simple system matters more than a powerful one.

Once the rules are on paper, the Sonos side is mostly scheduling. Sonos Pro lets a business schedule music by the hour, day or week and set volume limits remotely. We build the day around the stipulated hours rather than around what staff feel like at 11 p.m.: quieter mornings, a background lunch, a fuller dinner, and a late block with a lower cap that starts before the openable fronts have to close. The example below is how one might look.
Sooner or later a successful room wants a DJ night, a band or a later close. That is a change to the method of operation, and it goes to the board and the State Liquor Authority before it comes to us. We help with the design so the application can say exactly what would change, and we hold back the hardware until the decision is in.

A home system has one household. A business system has an owner, managers, a changing cast of staff and a room full of customers with phones, and the most common reason a well-installed bar system ends up too loud is that the wrong person could change it. Sonos already separates these people, if it is set up to.
Owner and manager. The Sonos account sits with the owner, and the owner or a named manager holds the settings: volume limits per product, EQ and Sub level, schedules, and the list of products in the system. On Sonos Pro, the dashboard adds admins you invite and lets you limit employees to the features you choose. We change any password a previous installer or staff member used at handover.
Staff. Sonos describes Guest Access as letting devices on the same Wi-Fi network control playback, volume and grouping without access to administrative features, and it is on by default. That is exactly the right level for a bar tablet: skip a track, move the music to the back room, turn down for a toast, but never above the cap and never into the EQ. The cap is the guard rail; Guest Access is the reason the guard rail stays where it was put.
Customers. Customers should have no way in at all. Guest Wi-Fi for customers runs on a separate network that the speakers are not on, and on Sonos Pro the line-in and AirPlay 2 features can be disabled so nobody can stream from a phone at the bar. A business that also has a customer TV area keeps the soundbar for that screen on the same managed system, so it follows the same caps and schedule.

Owners, managers and residents here ask us things we are not asked elsewhere, mostly about licences, staff and the people upstairs. The long answers are below, grouped by who is asking; quick practical points sit in the FAQ near the end of the page.
It changes almost everything except the brand. Background-only is a common stipulation in New York licence decisions; the State Liquor Authorityโs own meeting agendas record approvals “subject to” it, and operators who later want a DJ or live sets have to file a change to their method of operation. So the system is built so that background is what it naturally does: many small speakers spread through the room at low level rather than two big ones near the bar, a Sub left out or kept modest, no DJ inputs or line-in jacks left where anyone can plug in, and per-room volume caps set below the point where conversation has to be raised. We write the caps down with the date we set them. If the room later earns a different method of operation, we revisit the layout rather than just raising the limits.
Different jobs, done in order. The engineer measures, models and writes the recommendations: how much the building lets through, what the floor-ceiling needs, where speakers may and may not go, what levels to aim for. We build the audio system to that report, with speakers where it says, mounts and isolation it calls for, and caps it can test against. Where there is no engineer yet, we give you a written layout so the engineer has something specific to review. We do not certify that a room complies with the Noise Code; that measurement belongs to the engineer, and on a violation the city wants measurements, not an installerโs opinion.
Treat it as counting. The Community Board 1 wording is plain: “No speakers or live music in backyard. No background music.” A Move 2 or Roam 2 is a speaker whether it is screwed to a fence or carried out on a tray, and stipulations are written into the method of operation of the licence, which is what an inspector or the SLA reads. If your agreement allows something different for private events, follow its exact words. Otherwise we set the system so the yard has no room in the app at all, and keep portable speakers on their charging bases indoors, which removes the temptation on a busy night.
Plan before, install after. Design work costs little and helps the application: a layout, the products, where a DJ would connect and how the rest of the room would be capped while they play. Physical changes that only make sense for the new method, such as a booth input, a bigger Sub or extra speakers, wait until the change is approved, because an SLA agenda can approve a request with new conditions or not at all. Until then the current stipulations apply every night, so the system stays set for background music even if the hardware for the next stage is ready in the stockroom.
Mostly, yes. In the ordinary Sonos app, volume limits, EQ and Sub level are settings that need account access, while Guest Access, on by default, lets anyone on the same Wi-Fi play, pause, change volume and group rooms without administrative features. So the bar tablet stays on Guest Access and only the owner or manager holds the account. The volume limit then caps what the staff slider can reach. Sonos Pro adds dashboard control of which features each employee can use and remote volume limits for the whole site. What no setting fixes is a bartender with the account password, so we change it at handover.
No. ASCAPโs licensing guidance answers the exact question: you need permission to play records or tapes in your establishment. Buying a record gives you the right to listen to it, not to perform it publicly. The narrow exemption in that guidance covers radio and television reception in certain eating, drinking and retail places of limited size, with a limited number of speakers or TVs, no admission charge and no retransmission to another room. A turntable feeding Sonos speakers is outside it. The practical answer is a licence from the performing rights organisations, or a commercially licensed service for everyday background, with the records saved for when the licence covers them.
Usually not, though it is worth checking. Sonos says its own Sonos Backgrounds service streams at 128 kbps, about 60 MB per hour, which is fine for music under conversation but can sound less open than a high-quality home stream on a quiet afternoon. More often the cause is the room: speakers high on a bare wall, a Sub switched off, or a volume cap set so low that the music sits underneath the roomโs own noise. We check placement, Trueplay where the product supports it, and EQ before anyone blames the service. If it still sounds thin, try the other commercial services Sonos Pro connects to and compare at the same level.
Yes, that is what the Sonos Pro dashboard is for: Sonos describes monitoring multiple locations and individual products from one place, scheduling music for every opening hour, and setting volume limits remotely. We set each space up as its own room or zone, with the rooftop schedule and limit matched to whatever the licence and any community agreement say about outdoor hours, and the lobby running quieter than the bar. Staff permissions are set per role. The one thing we keep separate is anything a guest can reach: guest Wi-Fi never shares a network with the speakers.
Four things, ideally before the lease is signed. What the ceiling is: original tin or plaster on joists, a newer drop ceiling, or a concrete slab, because each carries vibration differently and decides how speakers can be fixed. What sits directly above: a bedroom over the bar area is a different problem from a stair hall. What the certificate of occupancy allows, since CB1โs questionnaire asks for it and asks whether your use fits it. And whether the landlord will let you add isolation or a new ceiling layer if an engineer recommends it. We can look at the space on a setup-only visit and tell you what the audio side would need.
Not the part that bothers most people. What comes up through a floor is mainly bass, and playing your own sound over it does not cancel it; at bedtime you would be adding volume to cover volume. Steady, broadband sound such as fan noise or rain can make the upper part of the barโs music less noticeable, and a sleep timer will turn it off once you are asleep, but it will not hide a kick drum. Noise-cancelling headphones, Sonos Ace among them, do better on low steady sound. The lasting fix is downstairs: placement, isolation and levels in the bar itself.
Ask for things that can be checked. Speakers off the ceiling that is your floor, or at least on isolating mounts. The Sub moved off the party wall and off the floor slab onto isolation, with its level reduced. More, smaller speakers at lower level instead of a few loud ones. Volume caps on every speaker that staff cannot override. A schedule that lowers the cap at the hour your bedrooms need it, and openable fronts closed on time. One Williamsburg resident on Reddit put the first step simply: ask the owner and the landlord to come up and hear it. If talks stall, the cityโs MEND NYC programme offers free mediation between residents and businesses when both sides agree.

Plenty of our Williamsburg customers are not businesses at all. They live in a railroad flat over a Grand Street restaurant, a loft above a studio, or a tower apartment over a gym, and they want a good system without becoming the problem they complain about. The building cuts both ways: the floor that brings the bar’s bass up to you also carries your Sub down, and up, to everyone else.
In a flat over a shop, the Sub stays off the floor joists over the business’s speakers and off the party wall, on a rug or isolation feet, with Sub level set after Trueplay rather than left at the factory setting. Night Sound, on Sonos soundbars, reduces the loudest moments and lifts quiet dialogue, which suits late TV in a building where the person above is asleep. Sleep timers end music on their own. And in a tower over a retail base, the same rules apply to the neighbour beside and below you, through slabs that carry a Sub’s impact better than they carry speech.
Our own system cannot cancel a bar’s bass, and we say so in the Q&A above. What we can do is explain, in specific terms, what a bar or café could change: speakers off the ceiling, an isolated Sub with lower level, more speakers at lower volume, caps staff cannot pass, and a schedule matched to the stipulated hours. Residents near the hotel in Greenpointers’ 2023 report went through 311, the precinct, elected officials and finally the community board’s licence renewal hearing. The city also runs MEND NYC, a free mediation programme launched in summer 2020 by the Office of Administrative Trials and Hearings and the Office of Nightlife for disputes between residents and nearby businesses, when both sides are willing.
If you are looking at an apartment over a bar, the time to ask is before you sign. Ask what the ground floor is licensed for, whether its licence has stipulations about music, and what time its openable fronts close. Community Board 1 posts liquor licence applications for public hearing, and the applicant must put up a notice at the premises at least ten days before the meeting, according to the board’s questionnaire. A five-minute visit on a Friday night will tell you more than any of it.

Nothing here is a sales pitch for a shop: Sonos products come from the retailer of your choice, Era 100 Pro only through Sonos’s installation partners, and AESS does not present itself as a Sonos dealer. Below are the products that turn up most on our Williamsburg jobs, with what each means for a business or for the neighbours.
The everyday speaker for cafés and shops: stands, shelves or a wall mount, Wi-Fi or a wired adapter. Sonos lists it, with Five, as a Sonos Pro speaker for commercial spaces.
Sonos’s first product for professional installation, shipped from January 28, 2025: PoE+ power and data on one cable, a surface mount with 30° pan and tilt and 360° rotation, a locking base plate and a secondary safety eyebolt. Sold in pairs through installation partners.
The larger standalone speaker for a room that needs more from fewer boxes, such as a gallery or a shop floor with high ceilings. Sonos also lists it among its Sonos Pro speakers.
Drives passive ceiling, wall or outdoor speakers, 125 watts per channel into 8 ohms. In Williamsburg storefronts it more often powers wall speakers than ceiling ones, for the reasons on this page.
Streams Sonos into an existing amplifier or a venue’s house system. Sonos says Sonos Pro can run on an existing non-Sonos sound system connected through Amp or Port.
Soundbars for the TV over the bar, the hotel lounge screen or the living room upstairs. Night Sound and speech enhancement on Arc Ultra and Beam keep dialogue clear at a low level.
Bass for a dinner room or a home theatre, used sparingly over a home: on isolation feet, off party walls and slabs, with Sub level set and then capped.
Portable speakers that charge indoors. Useful in a home; in a licensed business with a no-speakers backyard stipulation, they stay inside on their bases.
Headphones that can take over the TV sound from a compatible soundbar, for the late game in a flat where the person downstairs, or upstairs, is asleep.
Not hardware but the most useful piece for a business: schedules, remote volume limits, employee permissions, alerts and remote reboot, and commercially licensed music through Sonos Backgrounds.
| Option | Power and network | Mounting | Best Williamsburg use |
|---|---|---|---|
| Era 100 | Mains power at each speaker; Wi-Fi or wired adapter | Shelf, stand or wall mount | Cafés and shops under apartments, pop-ups |
| Era 100 Pro | PoE+ (works on standard PoE): power and data on one cable | Surface mount, 30° pan and tilt, 360° rotation, locking base | Restaurants and bars wanting fixed, tidy wall speakers with no outlets at each spot |
| Five | Mains power; Wi-Fi or Ethernet | Shelf or stand | High-ceilinged shop floors and galleries needing fewer, larger speakers |
| Amp with passive speakers | One Amp per set of passive speakers; speaker wire to each | Wall, ceiling or outdoor brackets | Rooms with existing wall speakers, or where an engineer approves the ceiling |
| Port into a house system | Port feeding an existing amplifier | In the rack | Venues keeping their own amplification but wanting Sonos Pro control |
The table is about the building, not the brand. Under a home, anything that bolts to the ceiling is the last choice; in a standalone building or a tower lobby, it may be the first. Where Era 100 Pro is chosen, our part is the cable, the switch ports and the setup, because the speakers come through Sonos’s installation partners.
These are the words that come up on almost every Williamsburg business job. Most of them are licensing terms rather than audio terms, which is rather the point of this page.
The description of how a licensed premises runs — hours, music, entertainment, occupancy — that the State Liquor Authority approves and that board stipulations are written into.
A condition the applicant agrees with the community board, such as closing hours for openable fronts or no music outdoors, signed and incorporated in the method of operation.
An SLA licence for a second bar inside an already licensed premises: often a back room, a basement or a roof, and usually its own Sonos room.
Recorded music at a level below conversation. A common licence condition; on a Sonos system it becomes a cap, a schedule and a speaker layout.
A Sonos setting, on by default, that lets devices on the same Wi-Fi play, pause, change volume and group rooms without administrative features.
A per-product maximum set in the Sonos app. Staff sliders stop there; only someone with account access can move it.
A semi-permanent Sonos grouping of several speakers that is controlled as one, useful for a dining room with many small speakers.
Sonos’s US subscription for businesses: a web dashboard for schedules, volume limits, staff permissions and multiple locations, with commercially licensed music.
The commercially licensed music service inside Sonos Pro, which Sonos says streams at 128 kbps and filters explicit content.
Power over Ethernet at the higher IEEE 802.3at level; Era 100 Pro is optimised for it and takes power and data on one network cable.
In the city’s PLUTO data, a lot classed as mixed residential and commercial building — in Williamsburg, home to about two in five residents.
Free city mediation, run by OATH with the Office of Nightlife, for quality-of-life disputes between residents and nearby businesses when both agree to talk.
We could not open Google’s AI Overview from the build system, so none of the claims below is quoted from it. They are seven things said about music in Williamsburg businesses and the flats above them in forums, product marketing, cost guides and local reporting, the sort of line an answer engine tends to repeat, and each is checked against a source in the list at the end.
Chatbots and forum answers often suggest a café simply play a playlist from a personal streaming account through its speakers. It is the easiest thing to do, and it sounds the same to the customer.
It is not the same in law. ASCAP’s licensing guidance says a business needs permission to play recorded music, including CDs, records and digital files, and Sonos itself says playing music in a business generally requires commercially licensed music. Personal streaming terms are written for personal listening.
In Williamsburg, with hundreds of licensed rooms in two ZIPs, this is one of the first questions we ask. The answer is usually a commercial service, through Sonos Pro or one of the services it connects to, set up in the owner’s name.
Cost guides and installer marketing often present ceiling speakers as the clean, professional option for any commercial room, and in an office tower or a standalone building they often are.
In a storefront whose ceiling is the floor of someone’s bedroom, they are the speakers most firmly connected to that bedroom. Community Board 1’s own questionnaire asks applicants whether they will follow a sound engineer’s advice “including placing speakers on the floor of the establishment.”
So the professional choice depends on what is upstairs. Under homes, we start with stand and wall mounts, Era 100 Pro on surface mounts, and isolation, and leave cut-in ceiling speakers to the rooms where an engineer says the ceiling can take them.
“Background music” sounds harmless, and many applicants describe their plans that way to a community board in good faith.
But background is a description of intent, not a setting. The State Liquor Authority’s agendas record approvals conditioned on recorded background music only, which an operator then has to keep to every night, and the city’s commercial music rule tests the low-frequency bands separately, so a quiet-sounding room with a busy Sub can still fail inside the flat above.
We turn the phrase into numbers: a per-room cap, a Sub level, an evening setting and a written record of when they were set. That is what makes “background” something a manager can actually keep to.
When a rooftop or club draws complaints, the usual answer in the news is soundproofing. The hotel owner in Greenpointers’ 2023 report said the business had built soundproof walls and “encapsulated the roof completely.”
Residents still described bass, and a reader comment under the article made the point that no engineer can guarantee immunity from bass travelling through shared walls. Enclosures help most with voices and the upper range; low frequencies get through structure.
The audio side has to do its part too: Sub level, speaker count and placement, caps and schedules. In that same report, the owner said he had asked managers to turn down the bass. That is a setting we lock so it stays down.
Most staff can, and the Sonos app is easy to learn, which is why so many guides suggest just installing it on the bar tablet and every manager’s phone.
Easy is the problem. With full account access, anyone can change the volume limit, the EQ or the schedule, and on a busy night someone will. Sonos separates this already: Guest Access gives playback, volume and grouping without administrative features, and Sonos Pro lets an owner restrict employees to chosen features.
We set the tablet to the guest level, keep the account with the owner, and leave a one-page sheet so staff know what they can do instead of discovering what they can break.
Simple setups group everything so one tap plays music everywhere, and for a small café that is fine.
A Williamsburg hotel is several businesses in one licence: a lobby, a restaurant, often a bar on the roof with outdoor hours that differ from the indoor ones. Hotel rooftop bars here sit as high as the 22nd and 23rd floors, above a neighbourhood of homes.
We build each space as its own room or zone with its own schedule and cap in the Sonos Pro dashboard, so the rooftop can end at the time its licence or agreement says while the lobby carries on quietly.
Residents above a bar are sometimes told, half seriously, to fight fire with fire and play their own music louder.
It does not work on the part that disturbs sleep. What comes up through the floor is mostly bass, and adding your own sound over it raises the total level in your bedroom rather than cancelling anything. Steady broadband sound can mask some of the upper range, and noise-cancelling headphones help with low steady sound.
The lasting fixes are downstairs, and they are specific: speakers off the ceiling, an isolated and lower Sub, caps and schedules. If conversation has stalled, MEND NYC offers free mediation between residents and businesses.
Photograph the stipulation page, then the ceiling, and tell us what is upstairs. From those three things we can say where speakers belong, who should hold the controls and what the Brooklyn list makes it cost.
To price a Williamsburg space we mostly need five things: what kind of room it is, who or what is above and below, any wording in the licence or lease about sound, which Sonos products you own or want, and where the internet arrives. Expect a written figure the same business day, or ring (347) 934-8335 if you would rather talk.
Received. Someone from AESS will call or email a figure before close of business. If your music has cut out in the middle of service, don’t wait for us — phone (347) 934-8335.
The six steps are the same for a pop-up on Bedford Avenue, a hotel on the waterfront and a railroad flat over a Grand Street restaurant. The first two happen before anyone chooses a product, and they are the two that make the difference in Williamsburg.
We start with the paperwork that limits the sound: liquor licence stipulations and method of operation, the certificate of occupancy, any community agreement, and for homes the lease or the buildingโs alteration rules.
We find out what sits over the room and next to it, which walls are shared, and where the busiest hour falls, before choosing any speaker positions.
Speakers go where they can serve the room at low level: on stands, walls or isolated mounts rather than the ceiling that is somebodyโs floor; the Sub off party walls and slabs.
Network and speaker cable in raceway or concealed routes, PoE+ ports for Era 100 Pro, and the speakers kept off any guest Wi-Fi network.
Trueplay where supported, Sub level and EQ by ear, per-room volume caps, schedules matched to the stipulated hours, and staff on Guest Access or Sonos Pro roles.
We play your music at the busy-hour setting, listen from the sidewalk and, where a neighbour is willing, from upstairs, then leave the manager or household a one-page record.
Customers usually tell us where they are by naming one of the places below. Our crews cover all of it: north to McCarren Park and the Greenpoint line, south past Division Avenue to Flushing Avenue, and inland from the river across the BQE.
Opened in 1903 and carrying the J, M and Z trains to the Lower East Side. Its arrival made Williamsburg, in Wikipedia’s account, the most densely populated neighbourhood in the city, and built much of the storefront housing on this page.
The waterfront park on the former sugar refinery site, opened in 2018, and the refinery building itself, landmarked in 2007 and now offices inside its brick shell, with residential towers around it.
The 36-acre park on the Williamsburg–Greenpoint line, with a pool that opened in 1936 and reopened in 2012. Summer concerts there in 2006 to 2008 later moved to the waterfront.
Music venue, bowling alley and restaurant at 61 Wythe Avenue, opened July 7, 2009 in the former Hecla Iron Works building, with a 600-capacity music hall.
George B. Post’s domed bank at 175 Broadway and Driggs Avenue, opened in 1875, an exterior landmark since 1966 with its banking hall an interior landmark since 1996, and an event space since 2014.
The hotel whose Westlight bar sits on the 22nd floor, with the Turf Club above it on the 23rd: a reminder that in Williamsburg the loudest room can be the highest one.
We also install in Greenpoint, East Williamsburg, Bushwick, Clinton Hill and Bedford-Stuyvesant, and our other Brooklyn neighbourhood pages cover Brooklyn Heights, Park Slope, Cobble Hill and Ditmas Park. Across the East River, the closest neighbourhood page is Long Island City.
Williamsburg is priced on our Brooklyn list, which is the base price area for the whole company: no neighbourhood surcharge and no parking line. Every number below is already published on that list. Anything that depends on a ceiling, a cable route or an engineer’s report is written up after a look, and nothing is added on the day without your agreement.

National averages versus a Williamsburg quote. A cost guide prices an average room. It cannot know that your ceiling is the floor of a bedroom, that your licence says background music only, or that staff need guest-level control. Every line we charge is on our Brooklyn TV mounting price list.
Most Williamsburg bookings fit one of three bundles. Think of them as worked sums rather than offers: published lines at the Brooklyn base rate, plus a wall line only if your particular wall calls for one.
$125
The Sonos setup line on its own: every product you own joined to one system, rooms named for staff, a licensed or personal music service signed in, Guest Access for the bar tablet, and caps and a schedule entered with you. Right for a café with freestanding speakers already in place.
$338.99
The soundbar that suits the screen — Arc Ultra, Beam or Ray — fixed beneath it ($129) on our Sanus bracket ($84.99), and the system set up around it ($125). Wall lines go on top where they apply: plaster $45, brick $65, concrete $75.
$507.99
Standard with one addition: a $169 in-wall power and cable kit so nothing hangs below the screen, which needs a hollow wall. Exposed brick or concrete gets the $59 painted cover instead, lowering the total.
If you already have a mount you trust, whether Sonos’s own Arc Ultra mount or a bracket rated for the bar’s weight, the charge is labour only: $129 to fit the soundbar, the line for your wall surface, and $125 if the system also needs setting up. The mount stays under its maker’s warranty, and if it looks wrong for old plaster or brick we say so before drilling and offer our Sanus bracket at $84.99.
Speakers spread through a dining room, Era 100 Pro on network cable, or wall speakers on an Amp are priced zone by zone after a site visit, because a storefront under apartments and a tower lobby need very different mounting and cable. Each zone falls inside the $800–$2,500 whole-home audio range AESS publishes, and the written quote lists every zone so you can do the dining room now and the back bar after the licence change.
Usually three pictures are enough: the ceiling, the wall the screen or speakers would go on, and the licence stipulations or lease clause. Most written figures go out the same day.
Businesses here rarely call us for sound alone. A fit-out, a new screen over the bar or a network that keeps dropping usually comes with it, and one visit saves setting up twice. These are the pairings we see most, every one priced on the Brooklyn list.
The borough page above this one, built around tall rowhouses, owner-and-tenant houses and rear gardens.
Soundbars from other makers, hung in lofts, tenement flats and towers by the same crew.
Hanging the bar or lounge screen on the same visit, so screen, soundbar and cable route are decided together.
Network runs for PoE speakers, back rooms and a wired link for the Sonos system.
Backbone cabling for converted buildings, hotels and multi-floor venues.
Cameras for bars, shops and building entrances, cabled along the same routes.
Door entry for walk-ups, lofts and buildings with shops below.
Keypad and app locks for shopfronts and the flats above them.
Fobs and codes for staff doors, back offices and stockrooms.
Intrusion alarms for businesses and homes.
Larger venue and event sound beyond what Sonos is designed for.
Separate staff, guest and speaker networks for a business.
Lighting and schedules that can include Sonos rooms.
Arrival windows, rescheduling, return trips and setup-only billing.
What follows is a working routine, not an anecdote: the order in which a Williamsburg business visit actually runs, whoever the customer happens to be.
Before we look at a speaker, we ask for the paperwork: the licence and any stipulations, the method of operation, and the certificate of occupancy if it is to hand. We read the lines about music, doors, hours and outdoor space, and we copy the exact hours into our notes. Then we go and look up. We find out what the ceiling is made of and what is directly above it, and if the owner knows a neighbour upstairs, we ask whether they would let us listen from their side at the end. We note which walls are shared, where the openable fronts are, and whether there is a yard or a roof. Only then do we talk about products. At the end of the visit, with the room at its busiest-hour setting, we stand on the sidewalk with the manager, then in the back of the room, then upstairs if we are allowed, set the caps from there and write down the date and the numbers.
The fixed parts come from the Brooklyn list: $125 to set up the whole Sonos system, with rooms named, music services or a commercial service signed in, Guest Access and volume limits set. A soundbar over the counter TV is $129 to mount plus $84.99 if you need our Sanus bracket. Ceiling or wall speakers on an Amp, or Era 100 Pro speakers on network cable, are priced per zone after we see the ceiling and the cable route; our published whole-home audio range is $800 to $2,500 per zone installed, and the written quote shows where each of your two rooms falls in it.
No. Sonos Pro is a subscription you take out directly with Sonos, and Sonos lists it as available in the United States and requiring the current Sonos app. We set the system up so it works with your Sonos Pro account: rooms and zones named, schedules and limits entered with you, staff permissions set. The subscription, its plan and any music service inside it stay in your name and on your card, so nothing breaks if you ever change installer.
It is billed on the Brooklyn setup-only line: $195 for the first hour, then half-hour blocks. Moving a few speakers, lowering limits or rebuilding a schedule usually fits in the first hour. If the board asks for new mounting or cable, for example taking speakers off a ceiling and putting them on stands or a wall, we quote that part in writing first, using the same price lines as the original job.
We can do the parts of the job that are ours. Sonos sells Era 100 Pro in pairs through select partners specialising in professional installation, and AESS is not presented here as a Sonos dealer, so the speakers come from that partner. What the speaker needs from the building is a network cable run and a PoE+ switch port, since it takes power and data on one cable. Our licensed crew runs and tests that cabling, mounts the surface mounts if you want us to, and sets the system up in the app.
Yes, and it changes the product choice. We favour freestanding speakers, such as Era 100 or Five, on shelves or stands, a soundbar placed on a console at $79 instead of wall-mounted, and no cut-ins at all, so the space is returned as found. The system is registered to your business account, not the address. When you move, a setup-only visit at the next location reconnects it to the new network and resets the limits for the new room.
Yes. At the end of the visit we walk the manager and whoever is on shift through what they can and cannot change: how to start and pause, move between rooms, use the agreed evening setting, and what to do if a speaker drops off. The manager gets a one-page sheet with the room names, the caps, the schedule and the account owner, so a new hire does not have to guess.

Every number about licences, homes and buildings on this page can be traced to one of the sources below; where we show a percentage or a total, we worked it out from the published counts ourselves. Prices are the exception: they come only from the AESS Brooklyn list.
A silent system on a busy night is rarely a hardware fault. Far more often the router was swapped, the app updated, the tablet reset or the schedule deleted. Ring (347) 934-8335 for the next two-hour arrival slot; an hour or two on site usually has the room playing again.
