Polk Audio PSW108 10" Powered Subwoofer
The Polk Audio PSW108 subwoofer is the most powerful sub in our testing, and it's plenty loud enough to shake the whole house. A removable grille and easy-to-install integrated keyhole make it a snap to wire up, though the price puts it about on par with the competition.
Polk Audio RC80i 8-inch Premium 2-way In-ceiling Speakers
Sound and quality for the Polk RC80i are near the top in our entire round-up of wireless on-ear headphones. The sub delivers solid bass, but it's a bit tinny and suffers from noticeable signal noise.
Polk Audio DSWPRO 550WI Powered 10-inch Subwoofer
Useful when placed in a cabinet, the 10-inch Polk powered subwoofer pumps out bass loud enough to make your head move.
Polk Audio PSW505 12" Powered Subwoofer
Polk Audio's 12-inch subwoofer is the most powerful, distortion-free subwoofer we tested. It doesn't sound as good as Polk's other two-way speakers, but its sound comes in a close second, and its integrated home theater features make it the best for the money.

An extension to your home theater system, this sub delivers accurate bass. However, the 35 lbs of weight inhibits easy portability.
Polk Audio HTS12 (Brown) powered subwoofer
The Polk Audio powered subwoofer offers great bass and enough power to light up a small room. The downside is its poor design and limited features.
Polk Audio HTS10 (Brown) powered subwoofer
This sub did a good job of filling our medium-sized living room with bass, with plenty of punch for loud music and movies, but the bass got a bit muddy at higher volumes.
Polk Audio Polk React 7" Wireless Subwoofer
Polk has created one of the best-sounding sound bars we've tested, and this subwoofer is almost as impressive. Unfortunately, the subwoofer is paired with another, more expensive Polk speaker, so you'll need a reasonably high-end stereo or home theater system to fully enjoy Polk's sound.
