With blending audio/video into a room’s environment without cluttering it up a big issue among homeowners, one question might be, where can you hide that darn subwoofer? PSB Speakers answers with its CustomSound CWS10 Enclosed In-Wall Subwoofer System, which the company says combines the inobtrusiveness with controlled and precise bass performance.

The CWS10 is ideally partnered with PSB’s enclosed in-wall offerings such as the CW800E and CW600E for an ‘invisible look,’ the company says, yet these in-wall systems provide a level of performance equal to the acclaimed PSB Platinum T8 and T6 floor standing speakers.

After extensive research into the in-wall environment, PSB created a subwoofer design that works well with the unknown volume each wall presents and the typically less-than-rigid wall construction, the company says. It features high excursion woofers for the output levels that movie lovers demand. 

Using the same frame as the CW800E, the CWS10 uses two special 10-inch woofers. It is 38.5-inches long and 14-inches wide, but still only 3.75-inches deep for in-wall installation. To maximize performance in the limited depth of the in-wall enclosure, PSB uses a design that mounts the neodymium magnet structure in front of the woofer cone rather than behind. The neodymium iron boron magnet material allows the magnet structure to be reduced in size to where the magnet will fit in the relatively narrow volume contained in the woofer cone, the company says.

Also, since a typical wall cavity is not the best enclosure for bass generation, PSB has built a highly braced, fully sealed wooden enclosure for the CWS10. By controlling volume and rigidity of the enclosure and customizing the driver’s mass and magnet strength for this application, exceptionally musical, high output deep bass is assured, according to the company.

The CWS10 is a passive device ideally matched with the PSB CWA-1 (MSRP $699) subwoofer amplifier, the company adds. This dedicated 300-watt amp includes appropriate filtering and equalization control and is suitable for up to the highest performance home theaters, says PSB. The CWS10 Subwoofer mates to the wall with an aluminum extrusion-based flange and easy-to-use ‘dog leg’ mounting clamps, while a perforated metal grille completes the look and can be easily painted to match any decor.

The CWS10 In-Wall Subwoofer will sell for an MSRP of $2,499. Go to for more.
