Hello everyone, I read this forum every so often, and now I'm getting very close to purchasing my speakers. I pretty much know everything I want to get, yet, I need some advice on the subwoofer. My room is approx. 25x50 ft. For my speakers I'm going with Klipsch RF-7 for the fronts , RC7 for the center, RS7 for the surrounds , and RB5 for my rear centers. I might also do a second set of RS7 for the side walls since the Denon receiver I will be getting can do 9 channels. I'm going to be using either a Denon AVR4802, 5803(probably not this since its too darn expensive and I don't think the Klipsch speakers need this much power,but maybe I'm wrong you let me know, hehe), or possibly an AVR4803 (if denon decides to come out with is soon). I would think they would be since everything in their line up is already an **03 except for the 4802. Now onto the subwoofer question. Price is not really a problem for me in terms of the speakers because I'm getting an unbelievable deal. I can get up to 2 subwoofers. So my question is should I get just 1 RSW15 or should I get 2 of possibly the RSW 10, 12, or maybe even the 15. Thanks everyone for all the advice and help you can provide.
