I just bought a Denon 3805 7.1 reciever and am trying to decide what speakers to use for back channel.I have a 5.1 system set up in place now,RF3 front rc3 center and rs3 on the side rear and Paradigm 2200 sub.What speakears would work best for back rear channel?I found a real good deal on a pair of rb5 speakers.
