Need big sound, slamming bass and audiophile bass extension, but don't want to see where it comes from? Then the ISW-4 in-wall subwoofer is for you. Two long-throw 200 mm (8 in) drivers allow it to move the large volumes of air needed for high-quality low-frequency output. The ISW-4 is housed in its own sturdy back box for rock solid stability and minimum sound bleed, and is powered by the SA250, a separate audiophile standard
250W Class D amplifier.
