What are your thoughts on these speakers? I may be matching 2 sets with the RC 25 center. I can get the RB15 for about $170 per pair. Is this a good deal? I like the clarity of the sound at the store, but it seems no bookshelfs produce bass in stores. I can also get deals on JBL, Polk, and Infinity. Will any that have similar retail sound better than the Klipsch? I am replacing the JBL N24's, which I find to be a bit muffled, and I want a bit more midbass.
