Explosive Performance for Movies & Music

PSW108 fills in the bottom end of your home theater system. Relieve your main speakers from performing bass duty and let them work on the mids and highs. PSW108 is a great addition to any subwooferless system and will bring your movie watching experience to the next level. Here’s how it does it.

The PSW108 features a front firing port so you get the full bass impact focused directly at your seating area.

Polk doesn’t use cheap paper cardboard woofers. This is the real deal and part of why PSW Series subwoofers outperform the competition.

By using a state-of-the-art Klippel distortion analyzer, Polk engineers were able to optimize the woofer’s motor structure, voice coil alignment and suspension bringing you the best possible performance even at extreme listening levels.

A Polk perfected method of analyzing a speaker’s microscopic behavior with laser Interferometry. Polk engineers can tune out unwanted resonance and distortion with the right combination of materials, geometry and construction techniques. This brings you pure, distortion free sound.

Line- and speaker-level inputs, and speaker level outputs allow easy connection to any system.

Keeps the subwoofer from sliding across the floor when played at high volumes.

4 out of 5 eggsDecent deal

Pros: Nice sub with good power. Looks clean and sounds pretty good.

Cons: When watching movies I have to turn the bass down. This sub has some really annoying chuffing. With music it gets drowned out but in a movie it sticks out like a sore thumb. I am going to buy another one just to have two at a lower level to fix this issue. I am happy enough with the sub though, that buying another doesn't make me angry.

Other Thoughts: Bang for buck it is a decent sub. just turn it down for movies.
