I'm working on setting up a 5.1.2 system in my basement. This is what I'm thinking so far but I have a couple questions...\n\n\nall my speakers are in wall\/ceiling. RC85I for front and rear speakers, RC80I for Dolby ceiling speakers and VS255CRT for center.\n\nI am wondering first of all what height I should mount my rear speakers on the wall. I have heard about 2' above head level when sitting? The ceiling height is about 7' 4". Is having them near the ceiling fine or should they be closer to hear height?\n\nAlso, are my rear speakers far enough apart? Im not sure if they should match my fronts or not. I think they work well for main seating position which would be on the couch center with the tv, but if someone was sitting on the far end of the couch they would be outside the speakers. Just wondering if that is just something I will have to deal with when dealing with a longer couch. Based on studs I could move them outwards another 16" or so so the were more like this.... (My couch is right up against the wall btw)\n\nThose are my main concerns but any other feedback would be helpful, I'm very new at this. My tv and front speakers are already in and can't move so the only ones that could be adjusted are the ceilings and the rears.
