The ISW-4 is one of Bowers & Wilkins most innovative products and enables the home audio or music enthusiast to experience a liquid, audiophile standard of bass response, while also having the luxury of not having to see where it comes from. It's an in-wall subwoofer, that features two large, long-throw 200mm drivers, capable of moving large volumes of air at an outstanding speed, allowing for a deep and controlled low-frequency output.
