It can be installed, but the price has to be known in advance: one Ø90mm hole and one power point for every speaker, at a cost per speaker that is higher than wired. What a wireless cinema solves is not "sound quality" but the situation of "the room is already finished and I still want a system". Once the ceiling is closed, the tiles are laid and the cabinets are done, this is the route that does not require breaking anything open.
This article answers three questions: whether it can be installed, what it will cost you, and how far it differs from a wired system.
1. Three things to confirm up front, miss one and it cannot go in
| Prerequisite | Requirement | If it is not met |
|---|---|---|
| The ceiling can be cut | Gypsum board or aluminum panel, clear space of 70mm or more | Switch to wall-mounted speakers (surface mounted) |
| Power at every position | A 220V socket, close by | Tap a lighting circuit or an existing socket, an electrician is required |
| The 5.8GHz channel is usable | Clear of metal ceilings and load-bearing walls | Reposition the receiving end |
When all three are satisfied, a 5.1 set can be installed within one day; if one is missing, the plan has to change.
2. The numbers for the CW90
| Item | Specification | What that means |
|---|---|---|
| Cutout | Ø90mm | A little larger than a downlight, a standard hole saw can make it |
| Faceplate | Ø105mm | Once fitted, just a ring of grille stays visible |
| Maximum sound pressure | 111dB | Enough for a living room of 20 to 30 square meters |
| Power | 90W per speaker | Wireless transmission means no amplifier cable has to be run to the speakers |
| Transmission | 5.8GHz dedicated channel | Kept separate from the household 2.4G Wi-Fi |
| Price of the set | From ¥17,200 (5.1) | Includes the W10 subwoofer and the MS-1 player |
3. Where it differs from a wired system
| Wireless (CW90) | Wired (IW3max) | |
|---|---|---|
| Installation | Cutouts plus power, no cabling | Audio cable laid in before the boards go up |
| Stage it suits | Already renovated, partial rework | Mid renovation |
| Cost per speaker | Higher (amplifier and wireless module included) | Lower (passive) |
| Latency | 10–20ms | Practically none |
| Moving them later | Unplug the power and reposition | The cable is fixed, moving means re-running cable |
4. The installation order: can it be done in one day
- Layout (1 hour): set the five positions against the sofa and the television, keeping clear of joists.
- Cutting (1 hour): a Ø90mm hole saw, with the dust bag attached.
- Power (2–3 hours): tapped from the nearest socket or lighting circuit, an electrician is required.
- Fitting and pairing (1 hour): fit the speakers, power them up, press the pairing key.
- Calibration (1 hour): levels, crossover, phase, audio and picture sync.
Finishing in one day is the normal case; an old house with complicated power work may need two.
5. Four common concerns
- "Will wireless be unstable?" A dedicated 5.8GHz channel, separate from Wi-Fi. Metal ceilings and load-bearing walls block it, so the receiving end has to avoid them.
- "Can you see the latency when watching a film?" At 10–20ms, with the player syncing picture and sound, it is essentially invisible on screen; Bluetooth at 100ms and above is where it becomes obvious.
- "Every speaker needs power, will that look bad?" Leave the socket near the access hatch above the ceiling, or use a power box up in the ceiling, and in normal use it is not seen.
- "Can it be changed to wired later?" It can, but the cable would have to be run at that point, which amounts to renovating once more.
6. Who should not choose wireless
- Still renovating, able to lay cable in: wired is cheaper and more stable, there is no reason to spend more for convenience.
- Planning 7.1.4 or a large room: the more channels, the more wireless modules and power points, and the cost climbs quickly.
- A metal ceiling or large load-bearing walls overhead: 5.8GHz is blocked badly, so test on site beforehand.
- A very tight budget: at the same price, a wired system usually gives better speaker quality.
7. Frequently asked questions
Q: Do the wireless speakers need an amplifier?
The CW90 has the amplifier built in, and the set comes with the player and the subwoofer, so no separate AV amplifier has to be bought.
Q: Can it go into an old house without an earth wire?
The speakers need a socket with a good earth connection; if there is no earth, it has to be added beforehand, otherwise background noise is likely.
Q: Can just two speakers be installed for stereo?
Yes, but cinema effect starts at 5.1; two speakers suit background music better.
Q: Is it easy to add height channels later?
Add two more CW90 units and pair them again, but mind the upper limit on the number of 5.8GHz channels.
8. The matching configurations
For a renovated room the default pick is the CW90-W10 5.1 wireless set (from ¥17,200); for something lighter, look at the CW90+P10 5.1 wireless set; a single unit is the CW90.
In one sentence
A wireless cinema is the solution for a finished room, not a higher grade of solution. If cable can be laid in, go wired; if the ceiling is already closed and the walls are to stay intact, wireless is the route that leaves the finished work undamaged.
