I am new to the Forum and Klipsch products. I do know about their quality and I currently own a sub 12. My current system is a 60" sony lcd with an onkyo tx-sr706 receiver with the Bose cube speakers for the fronts, Bose center channel speaker and Bose bookshelfs for the surrounds. I am looking to switch out the fronts and center, the bose center just seems flat or not enough depth to it if that makes since. My room size is 18'wx20'l and I sit approx. 18 feet back from tv and speakers. One of the problems I am running into is the space for the center speaker. I only have just under 5" of height to place it in my tv stand. So for the center I was looking at the XL-23 center. For the front sides I am looking at F-3, Icon VF-36, Icon WF-35 or the Reference Rf-63. I know the rf-63 is probaqble the better of those speakers. But I need some advise with quality sound and performance. Also is the xl-23 would be good for a center channel, how it sounds and if any or all of these speaker choices will be better sounding than the Bose that I am using now. I do not want to down grade speakers, I think these are all probable better sounding though. Problem is I can not hear all these to compare and I need your advise. Also I am looking for black cases but I did find agooddeal on the RF-63 in cherry, but cherry does not match anything I have. I think this retail company is discontinuing carrying the cherry wood. But if Klipsch is then I would not be able to add to the system later and get it to match. Anyway can you guys that know your audio help me out!!!!
