In-Wall Subwoofers

Delivering perfect bass

The Bowers & Wilkins range of In-Wall Subwoofers offers an elegant method of providing full range sound in a fully installed system. High-performance audio meets flexible mounting options to create controlled, deep bass
anywhere that you want it.

In-Wall Subwoofers

Bass is a vital element of sound, which is why we have developed a brace of specially designed in-wall subwoofers for custom installation purposes. The ISW-3 and ISW-4 provide tight, controlled, yet deep bass without impacting on your living environment.
