$180 off Polk Audio PSW10 10" 100W Subwoofer

The PSW10 subwoofer fills in the bottom end of your home theater system so your main speakers only reproduce the mid and high frequencies, not perform bass duty, too. If you're looking for your first subwoofer, look no further than the PSW10. It's a great solution for completing your sound system and will take your viewing experience, movies, games and TV to a higher level of enjoyment.

PSW subwoofers outperform the competition with durable, resonance-free Dynamic Balance driver materials that stay stiff and move fast. You experience deep, musical low frequencies and thrilling effects with superior system blending.
