The room I will be doing my theater in has 7' ceilings. On each end of the ceiling running lengthwise there are airducts about 2'wide which brings the ceiling height to 6'6" at these two spots(7' in the middle between ducts. Actually there is only one duct on one end right now running lengthwise, but I plan to mirror this by adding another one on the other side of the ceiling running lengthwise as well to balance out the ceiling and get better acoustics. Would this be optimal to build a fake duct for acoustics?) room dimensions are 12'W x 22'L and fully enclosed. The room will iclude soudproofing as well. I have a 36" tube tv so I dont have to mount a projector or anything. I know this isnt ideal but will I still be able to create a good theater experience in this area with my plan?
