Hello, I've been planning a dedicated HT in my unfinished basement. I’d like to get some advice in regards to ceiling height. I’d like to avoid a drop ceiling (acoustic tile). The problem I'm running into is that by doing so, it leaves me with limited ceiling height and room dimension choices. The center of the basement is separated by steel cross beam and 3 steel support posts. I’d like to build a staggered stud wall under the steel beam. The bottom of the beam is exactly 7’ from the concrete floor. This will of course, leave me with a very low ceiling. I’d estimate a 6’ 6” ceiling by the time the 2x4 studs; resilient channel and 5/8” drywall are installed. I can avoid this by placing the wall outside of the beam instead of directly underneath it. This will give me a gain of approximately 6” of finished ceiling height but it will decrease the width of the room by approximately 12”. So, I have to choose between the following "finished space" dimensions Under the beam LxWxH 19' x 12' x 6'6" Outside of the beam LxWxH 19' x 11' x 7' I currently have a 65” Mitsubishi (wide screen) rear projection TV. My question is for those of you that have built your theatres. Would you prefer the extra couple inches of ceiling height or would you chose the extra 12” of floor space?
