Custom Installation ISW-4

See nothing, hear everything

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 audiophile­standard 250W Class D amplier the SA250 Mk2, the system keeps its cool
even when the music movie action is whipping up a storm.
