ISW-3 and SA250 Mk2
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-. 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
6.5in drivers, means that it can be placed in a variety of locations without causing
vibrations. Powered by a separate audiophile-standard 250W Class D amplier the
SA250 Mk2, the system keeps its cool even when you listening to demanding movie
soundtracks at high volumes.
