I just ordered Ascend 170's for L/R and a 340 for the center. I am thinking about putting them on top of the TV cabinet so I don't have to use stands. The cabinet is 6' 2" tall overall and 5' 7" wide. The shelf above the TV for the center speaker is 5' 2" off the floor.
My 4 surround speakers are in the ceiling above the listening area.
Are the new speakers going to be too high up there? Is 5' 7" enough separation for L/R? Would I be better off angling them down towards the listening area? If so, what's a good 'wedge' material to tilt them down?
