Whether you’re installing a new set of surround sound speakers, adding a second subwoofer for the ultimate home theater experience, or just need more heavy-hitting bass from your favorite music, the Polk Audio 400-Watt 12-Inch Subwoofer with Power Port Technology is the solution you are looking for.

The front-firing 12-inch driver with dynamic balance technology is optimized to provide clean, clear bass, better linearity, lower distortion, and greater durability. The power port floor-firing design smoothly transitions air flow from the speaker into your listening area for deep, extended bass impact while minimizing turbulence, distortion, and port noise.

Built-in controls for variable volume, low pass filter, and phase 0 to 180 degree for optimum bass levels. Set power toggle to auto on/off or DC control for fast and easy on/off power switching in the sub and other home theater equipment which is all easily accessible on the back panel. To top it all off this home theater subwoofer has curved edges that offer a sensual yet powerful look that fits with any home decor.

Up the booming bass in your music, movies, and shows with the Polk Audio 400-Watt 12-Inch Subwoofer with Power Port Technology.

I was skeptical at first. Nonetheless, I receive my polk 400 W subwoofer in the original packing and in perfect form. The company did an excellent job. Thank you for getting me a great subwoofer at a significant discount.
