First let me tell you what I've got and go from there. Got 2 Polk RTi12s and a yamaha rx-v371 receiver. Had them for a few months now and I must say music, movies, and games all come through crystal clear. My wonder is that it does not appear to have the bass that it ought to. Can it get loud and jam??? Yes, but it just doesn't boom like I think it should. Bass is turned all the way up..... Not sure what else to do really. I'm not trying to shake the foundation of my house but w/ those 3 woofers in each speaker I guess I expected a LOT more bass response. Ideas??
