Here are the Paradigm Reference speakers that I have: Studio 60’s V.2 Front Studio CC V.2. Center Studio ADP V.2. Dipole Side Surrounds Studio 20’s V.2. Rear Surround PW2200 Subwoofer I just purchased a DenonAVR4802 Receiver, which lets me chose between two sets of side surround speakers, Monopoles vs. Dipoles, for Music vs. Movies. So now the 20’s which I planned on using for the rears will be used for the side surrounds when listening to music and I’ll use the ADP’s for watching movies. My question is now what do I get for the Rear’s? Do I get another pair of 20’s for a true 7.1 setup? Or could I get away with getting another Studio CC for the rear surround, since I hear the rear channel is mono anyway can I use a single center channel speaker or would I be missing all that much with ? Then comes the questions about placement. Can I put a wide center channel on a single stand or would I need two side by side stands. Any thought or comments would be appreciated.
