Product Description

The Polk DSW PRO 400 uses an 8-inch woofer and powerful 180-watt amplifier to produce deep, authoritative bass. This advanced subwoofer features Polk's exclusive Feed Forward(TM) technology, which reduces audible distortion without limiting volume. You get quick, precise response throughout the sub's entire frequency range, even at ground-shaking volume levels. The Polk DSW PRO 400 also includes the Polk Room Optimizer(TM), an ingenious feature that lets you specify the location of your sub with one of four options — corner, mid-wall, in-cabinet, or mid-room.

DSW Pro 400 issues
We just received our second DSW Pro 400 subwoofer within a week from Amazon and both have not worked right out of the box. We received the first subwoofer last Friday 10/17/08. More >>

nice sub
I recently upgraded speakers to Polk RTi-A3's (front) and smaller Polks on the wall (rear). I was still using an old Audiosource sub, figuring that a sub is a sub, what's the difference? More >>
