To reproduce serious bass you need a completely different kind of loudspeaker, one which can cope with huge pressure. KF92 is engineered to blast out huge chunks of lower frequency energy, yet is subtle enough to pick out the delicate details of a double bass. KF92 ensures you don’t just feel the air move – you feel the sound move you.

Compact subwoofer delivers smooth, powerful bass from anywhere in the room
Feed forward distortion suppression technology allows higher maximum output without distortion or damage
Innovative front-firing mode lets you place the subwoofer just about anywhere
Add big bass to your next movie night
Are weak explosions sucking the excitement out of your action movies? Then pump a little life into movie night with the Polk DSW PRO 440wi. It uses an 8" woofer and powerful 180-watt amplifier to produce deep, authoritative bass. This advanced subwoofer features Polk's exclusive Feed Forward™ 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.
Sounds great no matter where you place it
The PRO 440wi also includes the Polk Room Optimizer™, 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. The Optimizer then automatically equalizes the sub's response to ensure smooth, clean bass from that position. You can easily access this function, as well as the volume control and phase switch, with the included remote, so you can fine-tune the bass from your favorite listening spot. Removable feet let you position the PRO 440wi for either front-firing or down-firing operation, whichever you prefer.
