ok, so due to recent life events i now have the following grouping of equipment that i want to utilize to its fullest. Help me figure out what i should do. TV- Mitsubishi 73" DLP WD73727 PS3 2x XBOX 360 Elite 1 XBOX HD DVD player Toshiba A30 HD DVD player Wii Receivers- Denon 4306 Pioneer Elite VSX-82TSX Mains- LSi 15's RTi 12's Centers - LSi C RTi A Surrounds- 2x FXi 5's 4x FXi 3's Subs- Polk PSW10 Velodyne SPL-800 My initial thought was to put the RTi towers in the rear for surrounds, but the couch would be directly in front of them, and i fear would block a significant portion of the sound. So my second thought is to somehow use all four in the front, is that possible or worth a damn? Would it sound like crap? The denon receiver has a 9.1 capability with the B output. I have enough surrounds for that... Or should I bi-amp the front? I have more stuff than I know what to do with. Help me out. What is the best set up for this equipment? Thank you.
