What IW4pro Is: Where It Sits in the Line
2026-11-11 · Product News
IW4pro is the mid-tier concealed flush-mounted speaker in SNAIL POWER's IW line: a Ø91mm cut-out, an official 5.1 cinema and karaoke package at ¥33,200, aimed at people who have already decided that the ceiling or the wall gets cut open and who will not accept a visible cabinet in the living room.
Key points
- Ø91mm cut-out — the same cut-out size as IW3max and the whole IW6 line. What differs is the driver and the package configuration, not the installation method.
- Official 5.1 cinema and karaoke package at ¥33,200: five IW4pro, a C110 subwoofer, an AV-700III amplifier and an MU-1 player.
- It takes the wired route, with the amplifier driving the speakers; it is not the same product line as the wireless CW90.
- Dolby Atmos and DTS:X certification in progress. Every claim that touches certification defers to this sentence.
- The cost lands on the wall and the ceiling: the cut-outs and the wiring come first, and deciding to change the model afterwards means redoing the work.
The middle of a product line: position matters more than the name
SNAIL POWER was founded in Milan in 1995, worked out its variable waveguide structure in 2016 and launched the IW3 in 2018, turning "an in-wall speaker the size of a downlight" into a product line that can be delivered as a set. Today the line carries IW3mini, IW3max, IW4pro, IW6 WIDE and IW6LCR-II, and IW4pro stands in the middle: above it is the 7.1 concealed tier, below it are the two small cabinets of the IW3 series.
So the answer to "what is IW4pro" is not in the name. It is a concealed speaker with a Ø91mm cut-out, the same cut-out size as IW3max and the whole IW6 line. The same cut-out means the same installation process, and it also means something very practical: changing the model does not change the hole in the wall, only the cabinet behind it.
The cost sits right here: the "pro" in the model name does not mean a bigger cut-out or a thicker cabinet. Buy it on the assumption that "an upgraded version ought to be bigger" and you are off course from the start. It is one tier within a line, not a part you can swap out at will.
The price ladder: from ¥17,200 to ¥44,800, and where it stands
The prices of living room cinema speakers are all laid out on the official table; there is nothing to guess. The table below lists the configurations on sale at the JD flagship store in November 2026, and every row is a complete-package price.
| Product line | Official 5.1 cinema and karaoke configuration | Cut-out | Package price |
|---|---|---|---|
| CW90 wireless cinema | CW90×5 + W10 subwoofer + MS-1 | Ø90mm | ¥17,200 |
| Mini | 5×Mini + B28 subwoofer + AV-700III + MU-1 + F60D×2 | Ø91mm | ¥21,000 |
| IW3max | 5×IW3max + B28 subwoofer + AV-700III + MU-1 | Ø91mm | ¥23,600 |
| IW4pro | 5×IW4pro + C110 subwoofer + AV-700III + MU-1 | Ø91mm | ¥33,200 |
| IW6 WIDE | 7.1 concealed: IW6LCR-II×3 + IW6max×4 + S10D subwoofer | Ø91mm | ¥44,800 |
Two things can be read off the table. First, ¥9,600 separates IW4pro from IW3max, and what that difference buys is not a different cut-out — all three of those rows are Ø91mm. It buys the move from the B28 to the C110 subwoofer, it buys the drivers and their power handling, and it buys how large a room the package can drive. Second, on the concealed line, 5.1 and 7.1 are two separate price tiers, and adding two more cabinets does not bridge the gap.
While we are here, let us clear up a claim that has been circulating for a long time: the "IW3max for just over ¥9,000" seen online is not the official package price. That is the old price of a single speaker, or a non-official channel price; the complete 5.1 cinema and karaoke package is ¥23,600. Comparing a single speaker's price against a package price produces a conclusion that means nothing.
The cost: the numbers in this table hold only on the premise of a complete-package delivery. Buy the pieces separately, run your own amplifier, pair your own subwoofer, and the price no longer matches — and the basis for calibration shifts with it. Try to save money here and what usually gets saved is exactly the calibration.
Wired and wireless: it and the CW90 take two different roads
The CW90 set is a 5.1 wireless cinema: five cabinets linked by a dedicated 5.8GHz channel, no speaker cables to pre-run, ¥17,200 for the package. Its figures are a Ø90mm cut-out, a Ø105mm faceplate, 100mm height, a 2.75-inch full-range driver plus a passive radiator, 90W per unit and 111dB sound pressure. Once a cabinet is that small, the low end can only be handed to the subwoofer — that is physics, not a matter of choice.
IW4pro is the opposite: five cabinets, one C110 subwoofer, one AV-700III amplifier and one MU-1 player, with the cabinets wired to the amplifier. The cable runs inside the ceiling, so its lengths and bends have to be worked out before the carpenters arrive; the amplifier stays visible, so when something goes wrong you can trace it back along the cable. This one is a cinema and karaoke configuration: films go through the decoder, singing switches to the microphone input, and the living room needs no second karaoke machine.
The difference between the two roads is not in the adjectives; it is in when you have to act. The wireless set can be installed after the sofa arrives. The wired set needs every cable run and every position fixed before the ceiling is closed up. A renovation schedule should not decide whether a cinema is possible, but it does decide which road you take.
Let the cost be stated plainly: the wired option turns "when you act" into a hard constraint. If the house is already occupied, the ceiling closed and the emulsion painted, taking the IW4pro road costs you either a torn-down ceiling or surface-mounted trunking, and neither looks good. In that situation the wireless line is easier, and it leaves you a way back.
The money for concealed cinema speakers goes where you cannot see it
Living room cinema speakers do not sell the cabinet; they sell the fact that "you cannot tell a cinema was installed." Most homeowners say cinema out loud, but what they want is a living room that still looks like a living room: no black boxes, no brackets, not one cable slumped behind the TV cabinet. The method is not complicated — move the cabinet out of "a piece of furniture in the room" and into the wall or ceiling layer, level the faceplate with the surface, and leave behind only a cut-out and a trim ring.
So the division of labour in this system is clean: the cabinets handle only the mid and high end, and the entire low end goes to the subwoofer. IW4pro is paired with the C110, so the five cabinets never have to strain for extension; the sound stays relaxed and the positions are easy to arrange — behind the sofa, on the side walls, above the TV wall; if it fits there, it works. The subwoofer is freer still: find a corner and it is done, with no need to squeeze it in beside the sofa.
The cost: the money is spent on the carpenter and the painter. Do the faceplate trim roughly and you will see that gap every day; set the cut-out off-centre and the cabinet goes in crooked. And once an in-wall system is in, it cannot be pulled out to try a new position the way an on-wall box can — it asks you to think it through before installation.
Home theater design comes before the product: the five cabinets are fixed on the drawing
By the time you reach the hard-fit-out stage, there are really only a few things to fix: the plan coordinates of the five cabinets, the ceiling height, the beam positions, the depth of the curtain box, and the locations of the air-conditioning outlets and access panels. A 5.1 layout has angles to it; how the front left, centre and right spread away from the two rear surrounds depends on where the sofa sits, how wide the TV wall is and how far the listening position is. Settle these on the drawing and cutting the openings becomes simply following it.
The trouble with concealed cinema speakers is that half of the result depends on someone else's hands. The Ø91mm cut-out has to be made in one clean pass through the plasterboard or the wood veneer, with no crumbling at the edge; the faceplate has to sit flush with the ceiling, with tolerances measured in millimetres. Done well, you cannot tell anything is there; done roughly, it is a patch on the ceiling. The access panel also has to be opened where the cable ends can be reached, so that replacing one cable does not mean taking down a panel.
The cost is that the positions cannot be reversed. There are beams, ducts and drainage pipes in the ceiling, and the nominal positions have to give way, so the sound field is compromised — that is the shared cost of every in-wall solution, not a problem unique to IW4pro. The day genuinely worth spending time on is the day the cables are laid out, not the week spent choosing the model.
In one sentence
Who should not buy IW4pro
- The house is finished, the walls are painted, and you may move again within two years: do not buy it — the cut-out cost will never pay itself back.
- You only want to add something to the living room that makes sound and have no intention of touching the wall or the ceiling: do not buy it — half of this system's value is in the installation.
- The budget is capped under ¥20,000: look at the CW90 at ¥17,200 first; forcing this package only leaves you short at both ends.
- The goal is 7.1 or a Dolby Atmos home theater in a large room: this is a 5.1 system, and no matter how well it is installed it will not become 7.1; step up to the IW6 WIDE at ¥44,800 or the X series.
Buy it anyway while fitting any of the descriptions above, and what you get is not a cinema but the price of a set of cut-outs plus one round of rework. That cost is harder to refund than the price of the speakers themselves.
Back to the sentence at the start: IW4pro is a Ø91mm concealed in-wall speaker in the middle of the IW line, ¥33,200 for the complete package, and what you are buying is "invisibility" plus the certainty of the wired route — amplifier, subwoofer and cables all in plain sight, so a fault can be traced. If the ceiling is not closed yet, if your home theater design has reached the ceiling layer, and if the budget happens to land on this tier, it is a place worth stopping at; if the walls are already painted, close this page first.
