Bowers & Wilkins ISW-4 In-Wall Subwoofer System offers big sound, slamming bass and audiophile extension remaining stealth in the wall. Two long-throw 200 mm (8 inches) drivers allow it to move the large volumes of air needed for high-quality low-frequency output. The ISW4 is housed in its own sturdy back box for rock-solid stability and minimum sound bleed and is powered by the SA250, a separate audiophile-standard 250 Watts Class D amplifier.
