Polk Audio DSWPRO400B PRO Series 360W 8" Subwoofer

Enjoy great performance that always delivers. This subwoofer truly lives up to its name with smooth bass response and innovative technologies. Feed Forward™ distortion suppression technology maximizes dynamic output of the subwoofer system without relying on slow-responding feedback techniques, so what you hear is quick, precise bass output with minimal audible distortion, even at ground-shaking volume levels. In addition, the Polk Room Optimizer (PRO) feature includes 4 push-button room equalization presets that correct for room boundary effects so you're assured great bass performance no matter where you place your sub. You'll also appreciate a state-of-the-art Klippel Distortion Analyzer, which optimizes the woofer's motor structure, voice coil alignment and suspension for the best possible performance, even at extreme listening levels. Other impressive features, such as a downward-radiating slot port, front-firing applications and a rock-solid MDF enclosure, mean the difference between disappointing and dazzling audio.
