I'm hoping someone out there can point me in the right direction for choosing a subwoofer for my home theater. My budget is around $500 and would like to get the best bang for the buck. I would consider myself an audio enthusiast as I have a good appreciation for quality sounding products. The home theater is set up in the downstairs family room, which measures appproximately 15'x25'.

I currently have Klipsch RB-25, RC-25, and RS-25 speakers for my front, center, and surround respectively. At first I wanted to buy a Klipsch sub just to have it match the rest of my speakers, but then realized I don't have to match timbre with a sub and perhaps there are better subs out there for less money. Nevertheless I've looked into the RW-10, RW-12, and KSW-12. Unfortunately there is no place around my area that has these subs so I can't listen to them. I've also considered the Infinity PS-12, Polk PSW12, and Boston PV700, but again, nobody in my area sells them so I have no idea what they sound like. I have to rely on reviews and second-hand testimony.

I would appreciate your opinions. Thanks.

John
