I found this guy over at meniscus audio. at $57 it looks like a good deal.

I know that the psw-505 retailed at $500 which doesn't really mean anything.

I was wondering if this subwoofer would out-perform the dayton classic 12 inch subwoofer http://www.parts-express.com/pe/show...number=295-204

This would be used at a christmas present to my father to replace the old 12in subwoofer he currently has, which bottoms out so effortlessly when he watches movies.

The new polk would be running off of around 200 watts. I would tune it around 26-28hz, it would be used strictly for movies. He doesn't need it to really shake things up as my mother hates loud anything. The room is L-shaped, not sure of the dimensions.

But what do you guys think of that woofer? I can't spend more then $100 so the RS line is out of the picture.
