Sophisticated Cave...maybe.

You won't regret it. The extra inches of ceiling height will be the biggest benefit (unless you're a hobbit), cost being a close second.

Depending on how wide it is between your bulkheads you could get longer drywall to avoid any butt joints in the ceiling. That would give you only factory edge seams and save you a lot of time and effort cutting/taping/mudding/sandings. Of course I'm guessing if your room is 11' wide with around 1' bulkheads on either side (give or take an inch or two), and you'll be running 2x3s perpendicular to the joists. Given that you'll be just shy of a 8' sheet. You could always build out your bulkheads so that the middle is 8' all the way down.

The same would still apply to the width if you ran the drywall the other way except that they don`t make drywall that is wider than 4' which would mean you`d have a huge butt joint running the length of the room.

You're right regret it and except for some wiring the bulkheads are framed out and the ceiling has been dropped down to the height I need so I will be able to start rocking soon. Thanks for the original suggestion to drywall. I have some new pics but I was having trouble loading them so I will do that another day

I'm interested in watching your progress. The dimensions of my room are almost identical (although I have 7 feet, period). Actually going to be an inch or two shorter with drywall installed.

You may really want to think about two layers of 5/8 with green glue in between. Green glue going to run you another $350 or so in costs but will supposedly help out quite a bit. Check out Ted's website, there is a wealth of info there. What are you using for lights?

Thanks for the tip but the inside walls are complete already except for the acoustical treatments which may be extensive. I will post more recent photos when I can get them to load onto this site again. The main problem which I knew about before I began this project was the narrow sound stage but am hoping to overcome that as best I can. With this build I was not concerned with the amount of sound leaving the theater even though I have insulated the walls because it is in my basement and I stepped the walls in 2 feet from the foundation walls as necessary. I will try to give more info as I go along.

Remember also that electrical junction boxes can not be hidden behind drywall and must be accessible.

If you correctly plan and wire your HT, there shouldn't be a need for any junction boxes at all. No matter how complex the wiring is.

i'm really not following the postive of a sheet rocked ceiling in a theater room vs. a high quality accoustical suspended ceiling

i have a purpose built theater room with an accoustical suspended ceiling, we went with the Sanddrift line from USG for the tiles. Over top of the tiles we laid R19 unfaced insulation

in a different home we have a very similar setup where the basement has a sheetrocked ceiling (granted no R19 above it)

if I compare and contrast those rooms the difference is night and day, the echo and such within the sheetrocked media room is much worse. From a noise transfer perspective the suspended also performs better. Not to mention the significant advantage in being able to access the ceiling if needed.

Is the something I'm missing, or is my perception broken? Perhaps I'm favoring a particular setup over another for some other reason? But via my ear I absolutely wouldn't do a hard cap in a media room.
