Bowers & Wilkins ISW 3 In-Wall Subwoofer

Full-Range In-Wall Subwoofer

Bass is a vital element in our enjoyment of sound. It’s true for both music and movies, and it’s as true for custom installation as it is for an audiophile’s two-channel hi-fi. Fortunately, thanks to Bowers & Wilkins, you can have a powerful and convincing subwoofer that's mounted in-wall, allowing you to enjoy full-range movie and hi-fi sound without the need for a bulky subwoofer cabinet sitting on your floor.

"When you consider the limitations of an in-wall / ceiling / floor / cabinet subwoofer, the performance is quite impressive… there aren't a ton of products that meet this need," reports Tom Andry, audioholics.com. "For the custom installer, the ISW-3 configuration options and flexibility is likely to be a big draw."

Incredibly Compact and Versatile

The Bowers & Wilkins ISW-3 is an incredibly versatile and compact in-wall and in-ceiling subwoofer, capable of providing high-quality bass output in spaces that may have previously missed out on this vital element, including kitchen cabinets! Yes, it's really that compact and truly that versatile.

Its balanced design, featuring 2 x 6.5" drivers, means that it can be placed in a variety of locations without causing vibrations. And the ISW-3 is not shrinking violet when it comes to amplification. Powered by a separate audiophile-standard 250W Class D amplifier (mandatory, sold separately), the rack-mount SA250 Mk2, the system delivers deep and satisfying bass with built-in subwoofer equalization. And it keeps its cool even when you listening to demanding movie soundtracks at high volumes.

The ISW-3 / SA250 Mk2 system has balanced XLR inputs and outputs, unbalanced RCA inputs and outputs, 1 x Neutrik® Speakon® 4-pole speaker connector, 2 x pairs of binding posts, and 3.5mm 12-volt triggers. Front-panel controls consist of volume, phase, crossover, bass extension, and EQ.

Note: The SA250 Mk2 power amplifier (sold separately) is mandatory for operation of this subwoofer system
