What It Looks Like When It's Done: CW90 Wireless Living Room (Video)
2026-11-11 · Featured Projects
CW90 is a 5.1 wireless cinema from SNAIL POWER: a Ø90mm cut-out, a Ø105mm faceplate, 90W and 111dB sound pressure per unit, ¥17,200 for the full set, made for living rooms that are already finished and whose walls no one wants to touch again.
The video runs 31 seconds, shot in portrait, and shows a living room that is finished and already in use. The question it answers is very specific: once a 5.1 system has moved into a living room, what is left that can still be seen. At the tier that starts from ¥17,200, this is the answer you buy.
Key points
- After installation, what can still be seen in the living room is one subwoofer and a few Ø105mm circles.
- The cut-out is Ø90mm and the enclosure is 100mm high, so it drops in as long as the ceiling void leaves 100mm of clear space.
- The wireless signal runs on a dedicated 5.8GHz channel, so retrofit buyers no longer have to chase walls for home theater wiring.
- The package is CW90×5 + W10 subwoofer + MS-1, ¥17,200 for the set.
- It is not suited to large spaces, and not to anyone chasing low-frequency extension.
After installation, all that is left in the living room is a few Ø105mm circles
The term "concealed cinema speakers" is easily read as "no speakers at all", which is not what it means. After installation, what remains on the ceiling or the wall is a Ø105mm faceplate — the same order of size as the trim ring of a downlight — plus one more W10 subwoofer on the floor. That is exactly the state of the living room in the video: not many audio components remain identifiable.
What a client usually wants is not a cinema system but "a cinema you cannot see". It sounds like a marketing line, yet it is a decision standard: when guests come over, the TV and the sofa are what they notice first, not the few circles in the ceiling.
The cost is right here: with something hidden, the commissioning window is short. Once the enclosure is sealed into the ceiling its position is fixed; if the angle is off or the spot is wrong, the only later option is a fresh cut-out in the ceiling, patched paint, filled seams and a hunt for the same paint color. The other bill that never appears on a quote is the finishing: let the faceplate and the ceiling drift a little in color, or the skim coat lose a little flatness, and those circles turn from "light fixtures" into "patches" at once.
31 seconds can prove the look; it cannot prove how it will sound in your room
Half the value of concealed cinema speakers is in the picture, so the finished state is worth filming: whether the grille sits flush, how much floor the exposed subwoofer takes up, how conspicuous those circles are on the ceiling.
The other half it cannot prove is the sound. The same model placed in an 18 m² bedroom, a 30 m² open-plan living room or a duplex with a 6-meter ceiling void gives results that differ widely: ceiling height decides how far the in-ceiling speakers sit from your ears, glass and tile decide how hard the upper midrange sounds, and how close the sofa stands to the wall decides whether the bass booms or stays tight. The video carries none of that measurement data, and it should not be used to infer it.
With living room cinema speakers, half is the equipment and half is the room it is installed in. In a living room that is already occupied, there is little acoustic room to move: the walls cannot come down, the ceiling cannot be changed, and what is left is placement, a rug, curtains and an AV receiver with EQ.
The cost: the order of "acoustics first, speakers second" only holds while the room is still bare. Come back to it after the furniture is in and you usually accept the situation as it is. This video is fit for judging "do I accept the look"; it is not fit for judging "does it sound good".
Home theater wiring always means chasing walls; what the 5.8GHz dedicated channel skips is the signal cable
Where retrofit buyers get stuck is very concrete: the ceiling is closed and no cable was left behind the sofa. Wired for new builds, wireless for retrofits — the two approaches solve the problem at different points in time.
CW90 runs on a dedicated 5.8GHz channel, not on the 2.4G and 5G public bands where Wi-Fi is always crowded. A dedicated channel is not zero interference, and that has to be said plainly: 5.8GHz penetrates walls less well than lower bands to begin with, and load-bearing walls, metal ceilings and large expanses of glass all eat the signal, so this belongs in the layout stage. Within one living room it is rarely a problem; through a wall or up one floor, do not count on it.
There are two costs. One: what wireless removes is only the signal cable; everything else remains — how power gets there, where the module sits, how the trunking runs, all confirmed one by one. That W10 subwoofer still has to stand on the floor, still wants a corner and still needs an outlet; if no power was left on the TV wall during the fit-out, a surface-run cable goes in afterwards. Two: delay, level and placement on a 5.1 system still need a person to set them; without calibration, wireless will not sound better than wired.
The judgment follows: already living in the room, go wireless; still at the carpentry stage with the ceiling open, wired is the easier road.
Inside a Ø90mm hole: a 2.75-inch full-range driver plus a passive radiator
Common in-ceiling speakers in this industry often call for a cut-out of 20cm or more, and 27cm is not rare. The CW90 needs a Ø90mm cut-out, a Ø105mm faceplate and 100mm of mounting height. What that difference decides is whether it can go into a ceiling that is already installed — not which one is stronger.
The driver is a 2.75-inch full-range unit with a passive radiator added. The benefit of full-range is that there is no crossover point, so voices and most of the midrange come out of one continuous driver; the passive radiator helps push the low end down another step. The physical boundary sits in the same place: a 2.75-inch driver cannot reach very low, and expecting 30Hz from it is unrealistic.
So the division of labor is clear: CW90 handles the midrange down into the lower midrange, and the W10 subwoofer catches the octave beneath it. With the subwoofer holding the low end, the full-range driver does not have to strain. That is where 90W per unit and 111dB of sound pressure come from — power that is kept under control, not a driver made bigger. SNAIL POWER was founded in Milan in 1995, worked out its variable waveguide in 2016 and launched the IW3 in 2018.
| Item | Value |
|---|---|
| Cut-out diameter | Ø90mm |
| Faceplate diameter | Ø105mm |
| Mounting height | 100mm |
| Driver configuration | 2.75-inch full-range + passive radiator |
| Rated power | 90W / unit |
| Sound pressure | 111dB |
| Wireless transmission | 5.8GHz dedicated channel |
| Package configuration | CW90×5 + W10 subwoofer + MS-1 |
| Full set price | from ¥17,200 |
| Certification status | Dolby Atmos and DTS:X certification in progress |
The cost is size. The low-frequency output of five 2.75-inch drivers only adds up to so much; push the living room past 35 m² or the ceiling above 5 meters and this set will feel tight, and the step up is the IW6 WIDE 7.1 package (¥44,800) or the X series. Also, 111dB is the rated sound pressure of a single unit, not a number to hit at home — in a small room the reverb gives out first once the level climbs.
What you buy from ¥17,200, and who should not buy it
The easy mistake on a living room cinema speakers quote is to read the speaker price as the package price. Two systems both called 5.1 can run from ¥17,200 all the way into six figures, and the gap lands mainly on the subwoofer and the AV receiver, not on those five speakers. The CW90 package is CW90×5 + W10 subwoofer + MS-1, ¥17,200 for the set.
Certification has to be put clearly: Dolby Atmos and DTS:X certification in progress. In progress means the approval letter has not been issued, and it cannot be used as if it had passed.
Another thing often overlooked is karaoke. This set is itself a 5.1 wireless cinema and karaoke combo system, one system with two uses, and the living room needs no separate KTV set. The cost: only the speaker layer is saved — microphones, a reverb processor and a song source are still another bill, and they still take up floor space.
Who should not buy it, in four cases:
- A living room above 35 m², or a ceiling over 5 meters: this set does not have the output, and forcing it only sounds empty.
- Anyone who cares about bass below 30Hz, or loves big-dynamic explosion scenes: a 2.75-inch full-range plus one subwoofer is not tuned for that.
- Anyone still renovating, with conduit that can be pre-embedded: wired is the steadier road, and there is no reason to carry an extra layer of uncertainty for wireless.
- Anyone expecting "install it and be done": every 5.1 system needs someone on site to set it up once.
One more budget line not to miss: from ¥17,200 is the price of this package, and it does not include the TV, projector, screen, acoustic treatment and installation materials, which together can cost more than the speakers themselves.
In one sentence: what it sells is "the living room is still a living room"
In-ceiling cinemas like the CW90 rely on waveguide directivity, a full-range radiating cone, a bass radiating cone and an absorption cone working together, so that more of the sound stays at sofa level and less of it runs upstairs. The cost is right here as well: it cannot guarantee that the neighbors above and below will not hear it. If the unit below is especially sensitive, a floating floor will do more than changing speakers — that is a structural problem, not an equipment problem.
In one sentence: what this system sells is not "how hard it hits" but "after the installation, the living room is still a living room". If that is the result you want, the money from ¥17,200 is well spent; if you want something else, paying more may not put it right.
Three exit conditions: a living room over 35 m², a want for bass below 30Hz, or no tolerance for someone coming on site to tune it once. Match any one of them and this set is not your answer.
