Okay, I have the Onkyo HTS-650 5.1 system. It includes the Onkyo R500 receiver, a 150 watt 8" sub, and 5 speakers. Here's my question, would buying a pair of Athena AS-F2s and put them as my front L and R speakers, and move my current Onkyo front L and R speakers to the rear. I would, of course, remove the smaller surround speakers and disregard them. I would leave my front center speaker the way it is. Would doing this make my sound significantly better? Or would it decrease my sound because each speaker would be different (not acoustically matched?)? The reason I ask is because my local Bestbuy has the AS-F2s on sale for $360/pair and I am considering getting them. Also, would my Onkyo R500 receiver be powerfull enough to really push these speakers? I'm not very familiar with power ratings and amps, and such... you absolutely think that the Athena AS-F2s are the best fronts I could buy for $360? Also, if you were to recommend a solid center speaker, which would you recommend and how much does it cost?
