Get to know this product.

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.
