Feel the rumble in your movies with this powerful subwoofer

Pump up the excitement on movie night with the Polk DSW PRO 550wi. It sports a 10" woofer driven by a muscular 400-watt amplifier that'll make your hair stand up during intense action sequences. 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 wall-shaking volume levels.

Sounds great no matter where you place it

The PRO 550wi 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 favourite listening spot. Removable feet let you position the PRO 550wi for either front-firing or down-firing operation, whichever you prefer.

Ditch the wires

Connect the PRO 550wi wirelessly to virtually any home theatre system in seconds using Polk's optional PWSK1 wireless kit. Just plug the wireless dongle into the sub's power plug, and connect the compact wireless transmitter to your receiver. The transmitter sends bass signals wirelessly to the sub with no delay and no compression, providing you with more placement options for enjoying big bass.
