Below are the real worries we hear on the phone before a Sonos booking, sorted into six themes: whether the network will hold up, whether the ceiling or wall will take speakers, whether the building will allow it, how it will sound to the neighbors, which products to buy and how it fits a rental. Cost, warranty and scheduling are in the FAQ further down.
Network and Wi-Fi in a crowded building
Why does my Sonos keep dropping out in my apartment building?
Usually because the signal between the router and the speakers is weak or crowded, not because a speaker is faulty. Sonos rates plaster and concrete as high-loss materials for wireless signals, and it lists other routers, extenders, cordless phones, baby monitors and wireless cameras as common sources of interference. In a New York building you have all of those at once, most of them belonging to neighbors. A speaker with a marginal link plays fine at 2 PM and drops at 9 PM when everyone upstairs starts streaming.
The fix is in the network, in roughly this order: move the router out of the hall closet if it is buried there, keep Sonos products at least 18 inches from other electronics as Sonos recommends, pick a channel the neighbors aren't crowding, and if a room is still unreliable, wire one Sonos product or add a wired access point. We test the signal in each room before and after, so you can see the change rather than take it on trust.
My building provides the Wi-Fi — will Sonos work on it?
Often not as it comes. Sonos's system requirements exclude guest networks and networks with a log-in portal, require the app and every speaker to sit on the same subnet, and don't support WPA or WPA2 Enterprise security. Building-wide Wi-Fi in amenity rentals is frequently set up in one of those ways, which is why the app can't see speakers that are plainly powered on and connected.
The dependable answer is your own router, connected to the building's network or to a separate internet line, with your Sonos and your phone on it. We set it up, move the speakers across and check that the app finds every room. If your lease or building management restricts adding a router, we will tell you that plainly before you buy more speakers.
Should one Sonos be wired to the router, and can you run that cable in a finished apartment?
If any room struggles on Wi-Fi, yes. Sonos lists a wired setup, with one or more products connected to the router by Ethernet at all times, as a supported way to build the system, and in mesh networks it says the wired Sonos must connect to the primary node. In a pre-war apartment with the router in one corner, wiring the soundbar or an Amp often settles the whole system.
In a finished apartment we run that cable the least visible way the building allows: inside a stud wall where there's a cavity, along baseboards or door casings in a slim raceway painted to match, or through a closet. Concrete and brick walls mean surface routing. If the router and the TV are on opposite sides of the apartment, a wired ceiling access point near the speakers can be the neater answer.
My router sits by the front door and the living room is behind two plaster walls — what then?
Then the router is in the wrong place for Sonos, and most likely for everything else too. Internet providers in the city usually install the router wherever the cable enters, which is often the entrance hall or a bedroom closet. Two plaster walls between it and the TV is exactly the situation Sonos's interference table warns about.
Options, from simplest to most involved: move the router to a central spot if the provider's cable can be extended; add a wired access point near the living room; or wire one Sonos product back to the router. What we don't do is add a plug-in range extender or a powerline adapter, because Sonos lists both as unsupported and they cause many of the dropouts we are called to fix.
Ceilings, walls and speaker wire
Can ceiling speakers go into a pre-war plaster ceiling?
In many rooms, yes, with care and a survey first. A Sonos 6-inch in-ceiling speaker needs an 8.25-inch hole and 4.73 inches of depth behind the ceiling; the 8-inch model needs a 10.125-inch hole and 5.32 inches of depth. In plaster on wood lath there's usually room between the joists, but the opening has to be cut slowly and the lath held so the surrounding plaster doesn't let go. Sonos's own installation manual tells installers to survey for studs, conduit, pipes, ducts and other obstructions before cutting, and to probe through a small pilot hole if unsure.
Where plaster is already sagging, cracked in a web pattern or sounds hollow across a wide area, we don't cut it; no speaker should hang from plaster that isn't holding on. We show you the spot, suggest the nearest sound location, or recommend a plasterer before the speakers go in.
My ceiling is solid concrete — are in-ceiling speakers still possible?
Not directly into the slab. Many post-war towers have poured-concrete ceilings with the finish skimmed straight onto them, and there is neither depth for a speaker nor a path for wire. That is a property of the building, not something a better saw can change.
There are three honest alternatives. A carpenter can build a dropped soffit along one side of the room, which gives a cavity for speakers and cable; kitchens and bathrooms sometimes already have a drop ceiling we can use; or the room gets wireless Sonos speakers on wall brackets that only need a nearby outlet. We look at the room and tell you which one fits before you commit to buying in-ceiling speakers.
How does the speaker wire get from the ceiling back to the Amp without opening every wall?
By choosing where the Amp lives first. An Amp in a hall closet, a media cabinet or a bedroom closet near the speakers keeps the wire short, and the run can often follow the joist bay the speakers sit in to a wall cavity that drops to the closet. In brownstones, the joists give clean runs front to back; side-to-side runs cross joists and need careful drilling or a soffit.
Where a run would mean opening finished plaster, we look for an existing path first: a closet ceiling, a chase beside a riser, the space above kitchen cabinets. Only when none exists do we suggest an access cut, and we tell you its size and position so a plasterer can be booked alongside. A cable path is also why some customers choose wireless Sonos speakers for one room and in-ceiling for another.
Will the Era 300 wall mounts hold on my wall?
Only if they go into a stud. Sonos describes its Era 300 wall mount as stud-mounting only and not for drywall, with a ball joint that swivels 15 degrees up, down, left or right. That matters in New York, where the spot you want for a rear speaker may be a plaster wall with no stud nearby, a metal-stud partition or brick.
We locate the framing before agreeing the position and adjust it a few inches if needed. On brick and concrete we use masonry fixings rated for the load and suited to the mount; where neither works, a floor stand or shelf is the better answer, and we will say so rather than force a bracket into a wall that can't carry it.
The building, the board and the landmarks
Does cutting ceiling speaker holes count as an alteration in my co-op?
Often it does, and you should ask before booking. Co-op and condo alteration rules exist for work that cuts through walls and ceilings or touches electrical systems, and trade coverage of New York boards notes they may regulate any work touching fragile or old walls, even cosmetic work. Speaker holes in a ceiling, and cable run inside walls, can fall under that, while a soundbar on two anchors or wireless speakers on a shelf usually do not.
Ask the managing agent whether low-voltage speaker work needs an alteration agreement. If it does, we supply the scope, speaker locations, product sheets showing cut-out sizes and our insurance certificate, so the board reviews a clear plan. If the answer is no, we still send the certificate and confirm the building's contractor hours.
My building is in a historic district — does the Landmarks Preservation Commission need to approve speakers?
For interior Sonos work, usually not. The Commission says an LPC permit is needed for interior work only when the work also needs a Department of Buildings permit, when interior work affects the exterior, or when the interior itself is a designated interior landmark. Ceiling speakers and low-voltage wiring inside an apartment don't normally meet any of those.
Outdoor speakers are a different matter. Anything fixed to a facade, a stoop or a roof visible from the street in a historic district may need review, because most changes to front and rear facades there do. If you want speakers on a brownstone's rear deck or garden wall, we check before drilling. This is general information, not legal advice; your building's counsel or the LPC has the last word.
When can the work be scheduled in a doorman building?
Inside the building's contractor hours, which in many co-ops are weekdays during business hours. Trade guidance on New York alteration rules describes the traditional window as Monday to Friday, 9 AM to 5 PM, with weekend work limited, and contractors typically arranging the service elevator at least 48 hours ahead. Your building may differ, so we ask when you book.
That shapes the visit. A soundbar and app setup fits comfortably in a building window. Several rooms of ceiling speakers may be split across two weekday visits rather than squeezed into one. We book the service elevator through the super or the front desk, and we tell you in advance if a weekend date you asked for isn't allowed.
Sound, bass and the neighbors
Will a Sonos Sub bother the people downstairs?
It can, because bass travels through floors and structure far more easily than voices do. Sonos's guide allows the Sub 4 in a corner, against a wall, or under furniture with at least an inch of clearance above it, and its wireless connection lets it sit anywhere in the room. That flexibility is useful in an apartment: the Sub doesn't have to go in the corner that drives the most vibration into the floor.
We try two or three positions with you, sitting where you watch, and keep the one that gives even bass at the lowest level. A dense rug or an isolation pad under it helps on wood floors. After Trueplay, we set the Sub's level in the app and show you the night-listening setting on the soundbar so late films stay in your living room.
Do in-ceiling speakers send music into the apartment above?
Some sound does go up into the ceiling cavity, and in a wood-joist building that cavity is shared with the floor above. How much reaches the neighbor depends on the ceiling, the floor above and the volume, and it is worth discussing before a bedroom or a late-night living room goes into the plan.
Practical steps: keep ceiling speakers for background listening in kitchens, baths and hallways, set a sensible maximum in the app, and use the soundbar and Sub for loud films. Where noise upstairs is a real concern, wireless speakers on wall brackets are often the better choice for that room. We would rather tell you that now than install speakers you can't use after 10 PM.
Choosing the gear
Arc Ultra, Beam or Ray — which one suits my living room?
Size the bar to the TV and the room. Sonos lists the Arc Ultra at about 46.4 inches wide and the Beam (Gen 2) at about 25.6 inches, both connecting to the TV by HDMI; the Ray is the compact model and connects by optical cable. A 75-inch TV over a long wall suits an Arc Ultra; a 50-inch TV in a narrow living room is usually better served by a Beam; the Ray fits a bedroom or a studio and an older TV with an optical output.
Check one thing before you order: which audio outputs your TV has. If it has HDMI ARC or eARC, an Arc Ultra or Beam connects with one cable and the TV remote controls the volume. If it only has optical, the Ray connects directly. Send us the TV model and we will confirm before you buy.
Do I need a Sonos Amp, or can I keep my receiver and add a Port?
It depends on what you are keeping. The Port is a streamer: Sonos describes analog and digital coaxial outputs to a receiver or amplifier, an analog input for something like a turntable with a built-in preamp, and a 12-volt trigger that wakes a third-party amplifier when Sonos starts playing. If you love your receiver and speakers, the Port puts them on Sonos.
The Amp has its own amplifier and drives passive speakers directly, which makes it the usual choice for in-ceiling and in-wall speakers. Reviews list it at 125 watts per channel into 8 ohms, with an HDMI ARC input for a TV. We will tell you which one your plan needs, and how many.
How many ceiling speakers can one Amp run?
Sonos says the Amp reliably powers up to three pairs of its architectural speakers, six in total, when wired in parallel. In practice that is one room with six speakers, or a pair each in three nearby spaces that will always play together, such as a kitchen, a dining area and a hall.
If rooms need different music or volume, they need separate Amps, because one Amp is one Sonos room. That is the decision we make with you at the walkthrough: which spaces will ever play separately, and which never will. It sets how many Amps you buy and where the speaker wire goes.
Does Trueplay work if everyone in the house uses Android?
Partly. Sonos says most of its products need an iOS device for Trueplay tuning. Its newer speakers — Arc Ultra, Beam Ultra, Era 100, Era 100 Pro and Era 300 — can tune themselves with quick tuning from iOS or Android using their built-in microphones, while advanced tuning, where you walk the room with the phone, is iOS only. Architectural speakers on an Amp are tuned through the app with a supported iOS device.
We bring a compatible iPhone and run advanced tuning in each room, which Sonos says takes about three minutes per room. The room has to be reasonably quiet while it runs, and if you later move a speaker or change a stereo pair, Sonos advises tuning again.
Renting and moving
I rent — what Sonos setup leaves no holes?
More of one than people expect. A Sonos soundbar on the console, a Sub on the floor and Era speakers on stands or shelves need no drilling at all, and wireless rears can sit on bookcases at the back of the room. The network work — router placement, channel settings, removing an extender — leaves nothing behind either.
If your lease allows small holes, the soundbar can go on the wall or on the TV mount, and a paintable cord cover hides the cable. In-ceiling speakers are for owners, or for renters with written permission from the landlord, because the ceiling openings stay when you leave.
We're moving apartments — can you take the system down and set it up at the new place?
Yes. We take down the soundbar and any wall mounts at the old apartment, pack the hardware with its cables, and reinstall at the new one with anchors for whatever wall we find there. The system then has to join the new Wi-Fi, which is where moves usually go wrong; we do that on the visit and retune each room, because a new room sounds different.
Ceiling speakers normally stay with the apartment, since they are built in. If you are leaving behind an Amp and speakers, we can remove the Amp from your Sonos account so the next owner or tenant can set it up cleanly.
