I have been considering purchasing new tower speakers. I have been looking at the difference in price, between the 2 vs. 3 way's. Seems to be a little bit of a jump. Therefore I am wondering, if there is a big (noticeable) difference in the way sound is reproduced. I don't have a store where I could go and listen to any speakers. I am looking at AudioPro, and Polk. I have a 5.1 Kenwood system. Can someone help me with this predicament?
