Phil A,
Thanks for the quick response. Currently, I am using Klipsch RF-7's for front, RC-7 as the center and RF-82's for the rear and RSW-15 as the sub. My room is approx. 23 x 13 feet. I'm using Cardas speaker cable to connect all the speakers, which works very well with the horns on the Klipsch. My preference is 80% 2-channel music and 15% multi-channel listening. Very rarely do I watch movies. I listen to mostly 70's to modern rock / alternative music (i.e. U2, Pink Floyd, Modest Mouse, etc.) at a medium listening level.
