The ISW-4 is an in-wall subwoofer with two long-throw 200 mm drivers. That excursion lets it move the volume of air quality bass requires.

The cones combine paper and Aramid Fibre. The mix keeps the diaphragm stiff without making it heavy, which holds the bass together at high level.

The subwoofer disappears into the wall. It needs a dedicated amplifier, which leaves the choice of power and settings open.
