This is a package with a Bowers & Wilkins ISW-4 in-wall subwoofer and an SA250 Mk2 subwoofer amplifier.
SUBWOOFER
Need big sound, slamming bass and audiophile bass extension, but don’t want to see where it comes from? Then the new ISW-4 in-wall subwoofer is the product for you. Its two long-throw 200mm drivers allows the ISW-4 to move large volumes of air needed for high-quality low-frequency output, but is nicely hidden away inside a wall. Powered by a separate audiophile standard 250W Class D amplifier the SA250 Mk2, the system keeps its cool even when the music movie action is whipping up a storm.
