So my M60TIs have the gold plates and I've removed them and run additional speaker wires to the SL + SR of the AVR, and chose BI-amp to yes in the AVR configuration. My speaker configuration is 5.1, two towers, a sub, a front and my rear bookshelve speakers are connected to RL and RR. My speakers are mounted at 4:30 and 7:30 from the listening position at ear level. Do I have to have two more speakers at 3 and 9 to get surround sound? Or does the AVR do (emulate) that when I select that as a listening mode(s)?
