See nothing, hear everything

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 165mm (6.5in) drivers, means that it can be placed in a variety of locations without causing vibrations.
