Polk Audio PSW10 (black)

Pros: Matches my Polk Audio Monitors in looks and sound.
10 inch Subwoofer
Removable grill

Cons: Port noise
Doesn't play lower than 35 HZ.

Summary: I got this Subwoofer on sale for $99 USD. I have to say it's worth the $99 but not the $199. I say that because it does produce a lot of port noise when the bass is loud and deep. It can't play notes lower than 35Hz. I know 8 inch woofer that can hit lower than that. It's a nice looking subwoofer matches the monitor series. It is loud for only being 100 watts. Has left and right RCA input jack for stereo receiver or for AV Receiver that give two sub out jack. I use this sub with a pair of Monitor 30's connected to a Harman Kardon Hk 3480 and I'm pleased with.
