32Hz-80Hz Sensitivity 96dB

Direct radiation 21" subwoofer Features SW121P 21" direct radiating subwoofer completes bass response with an impressive excursion control and high power handling capability. SW121P is designed to work at 1500 W (AES) continuous power and can handle peaks 6 dB higher than that (up to 6000 W) without damage. Because of its heavy duty DSS (Double Silicon Spider) suspension system, its double demodulating ring (DDR) and its over damped housing, SW121P can provide a tremendous amount of defined and controlled low frequency energy. An amplified version is also available (SW121A).
