Google's AI Overview could not be opened from the environment this page was built in, so nothing here pretends to quote it. Instead, we took seven statements that turn up again and again in cost guides, product listings, forums and installer marketing — the raw material answer engines draw on — and checked each one against a detached wooden house and a pre-war apartment in this part of Flatbush.
Claim one: "Put the router in the middle of the house and Wi-Fi will cover everything"
Home-networking advice usually starts and ends with router placement, and for a two-bedroom apartment that is sensible. It is repeated as if it applied to any home.
A Ditmas Park house can have a cellar, two full floors, a third floor under the roof, a porch and a garden a hundred feet deep. Wood passes Wi-Fi easily, but distance still wins, and the internet usually arrives at one corner of the cellar, not the middle of the house. Sonos does not support wireless range extenders or Ethernet over power lines, and in a wired mesh setup it wants the wired Sonos product on the primary router.
The reliable plan in a big frame house is one or two short cable runs — cellar to main floor, perhaps main floor to the second — feeding a wired Sonos product or an access point. In a wooden house those runs are among the cheapest parts of the job, and they make every speaker in the house steadier.
Claim two: "A covered porch counts as indoors, so any speaker will do"
Product reviews often show indoor smart speakers on porches and patios, and buyers reasonably assume a roof is protection enough.
Sonos's own placement guidance says speakers that are not waterproof may be damaged if exposed directly to water or left outside for extended periods. A porch roof keeps off falling rain but not wind-driven rain, humidity, summer heat under the ceiling or winter cold, and a porch speaker is out there for months at a time.
For a permanent porch zone we use Sonos's IP66-rated outdoor speakers on an Amp kept indoors. For occasional use, a Roam 2 or Move 2 carried out and brought back in is fine. An indoor speaker left on the porch rail all summer is the one choice we steer people away from.
Claim three: "Allow $500 to $1,000 for every room you add"
Angi's guide to whole-home stereo gives $500–$1,000 per room for additional zones, labor of $50–$100 an hour for jobs of two or three hours, and $100–$500 for wall or ceiling modifications. Cost summaries repeat the per-room figure as the price of multi-room audio.
It is a national average for an average house, and it treats every room alike. In a Ditmas Park house many rooms need nothing but a speaker on a shelf and the $125 Sonos setup; a parlor soundbar on plaster is a handful of published Brooklyn lines adding up to a few hundred dollars; and the expensive work — ceiling speakers, outdoor zones, network cable — is concentrated in two or three places.
Our written quote prices each room on its own line, from the Brooklyn list, so you can see which rooms cost almost nothing and which carry the real work. The AESS NYC audio page publishes whole-home audio at $800–$2,500 per zone installed, and your quote shows where each of your zones falls in that range.
Claim four: "Wiring a century-old house means opening up the walls"
Renovation forums are full of stories about old houses where every new wire meant cutting plaster, and the assumption carries over to speaker wire and network cable.
In a frame house with a reachable attic and cellar, most runs never touch a finished wall. Speaker wire drops from the attic into a bedroom ceiling or down an interior partition; network cable rises from the cellar into the main floor through a plate under a baseboard. The preservation architect who spoke to 6sqft about her Ditmas Park house put it plainly: modern services "can be retrofitted pretty well within a historic structure."
Where a cut is unavoidable — the opening for a ceiling speaker, say — we locate framing first, cut with the template, and tell you before we start that old plaster can crack. The point is that the cut is the exception, not the method.
Claim five: "Ceiling speakers are always the most discreet choice"
Architectural speakers are widely marketed as the invisible option, the one that keeps boxes off shelves and floors, and that is often taken to mean they suit every room.
In a new apartment with drywall ceilings that is usually true. In a Ditmas Park parlor with original plaster, a ceiling medallion or a beamed dining room, the cut-out is the least discreet thing you can do to the room, and on an outside clapboard wall an in-wall speaker leaks sound and cold air outdoors. Sometimes the most discreet choice is a well-placed Era speaker on a bookcase.
We use ceiling speakers where the ceiling is plain, the attic is above and the room is for listening — upper-floor bedrooms, kitchens, renovated rooms — and free-standing speakers where the room's original surfaces are the point.
Claim six: "Sonos can handle your event's microphones too"
Sonos's line-in on products such as the Era 100 and the Port is sometimes suggested as a way to plug in a microphone mixer for a party, a reading or a meeting.
Line-in audio is buffered before it plays so it can be sent to other speakers in the system; a Sonos community answer puts it simply: "There is always going to be a delay on the line-in." Sonos's settings include an audio delay option for exactly this reason, and owners report at least about 75 ms on the Era 100. A speaker at a microphone hears that as an echo.
For speech, a small PA with its own speaker is the right tool. Sonos stays in charge of the music, and the two can share speakers through a Port or a switch where that makes sense.
Claim seven: "It's your property, so outdoor music is your business"
Outdoor-speaker guides concentrate on weatherproofing and coverage and say little or nothing about who else can hear the result.
New York's noise code prohibits a sound reproduction device being used to create unreasonable noise, and a street of freestanding houses with open windows is where modest music travels furthest. A block party needs a Street Activity Permit and a separate NYPD sound permit. The tree at the curb is city property that Parks says no one may work on without a permit.
None of that stops a porch or garden zone; it shapes it. Speakers face your own seating, volume limits are set at the property line, and anything that involves the street goes through the block association and the precinct first.
