I'm able to get the Polk DSW 440wi sub for $155 new, and I was wondering if that can be beat. My room is about 12'x12x9, and I'll be using it with a Denon AVR-S500BT and Polk Tsx220B bookshelves. It will be 95% for music and the rest for gaming and movies. I listen to a mix of rap, EDM, rock, and classical music.
I can't say I'll need more than an 8". I'm moving from a klipsch promedia's 2.1 set and a pair of M-Audio BX8-D2, which had no sub. Blending with the speakers and accuracy are much more important to me. Thanks!
