Product Information

The ISW-3 is an incredibly versatile and compact in-wall and in-ceiling 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.

The 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! Its balanced design, featuring 2 x 6in drivers, means that it can be placed in a variety of locations without causing vibrations.

Powered by a separate audiophile-standard 250W Class D amplifier the SA250, the system keeps its cool even when you listening to demanding movie soundtracks at high volumes.
