I use 4 of these with a Klipsch WC-24 center channel and 10" Klipsch sub. I use my setup primarily for AV in our living room. I replaced an older set of Klipsch Quintet speakers that I really enjloyed. I have to say the clarity and crispness of the XB-10 blows away anything else I have heard in that size package. My wife will not tolerate speakers on the floor no matter how good they are. Soooo I brought these home and she absolutely loves the sound. She has even been buying BluRay movies so we can watch and hear the difference from ordinary DVD. These speakers sound absolutely crystal clear at low volumes as well as cranking up the volume level. I could not be happier with my choice and I will be adding 2 more for a 7.1 set up.
