Just moved into a new home and am trying to figure out speaker placement. Had a klipsch quintet 5.1 system in my old house along with a 10" reference series sub. I left the quintet speakers at the old place, but brought the sub with me. Thinking of just doing a 3.1 with some bookshelf speakers mounted on the wall to the left and right of the entertainment system. My question is, where would be the best place to set up a center channel speaker? Would it be ok to put a shelf on the wall and mount it just above the TV? The quintet speakers were small and im looking to upgrade this time to larger ones. My AVR is a Denon AVR-1600H for what its worth.
