My first thought in general would be probably not. What is your room size and how far will they be from you?
The room is 38x16. First row of seats is about 14 feet. So the heights would be roughly 14ft. The surrounds can be mounted on the side walls or ceiling. I prefer the ceiling looks wise but wall might be better sound wise. Either location would put them where they belong but the ceiling would put them at a height of 9ft. The ceiling is unfinished at this point. I'm saving for sound proofing material.
