The insurance company tore everything out (stage, riser, carpet, columns, and 2' of drywall from the bottom up.
So I get to redo it, but I want to put in more sound treatment this time. I am also looking for advice and comments.
The room is in the basement. It is 17' 4" wide by 26' 6" long. Soffits are 20" deep from the wall and a height of 7'. Center ceiling is 7' 9"
The walls are 2x4 with two layers of 5/8" drywall. There is a 1/2" gap and then another 2x4 wall outside with 5/8" drywall facing the rooms on the other side. So it is physically decoupled. The ceiling does not touch the joists which are at a height of 8' 11" from the floor. The room phsically touches the rest of the house in 3 points. (2 points on the ceiling that are rubber mounted to help support the ceiling and the door jam which touches the room and hallway. The door is 1 5/8" solid core with weather strip and is the weak spot in the room for leaking out noise. I plan to put a 1-2" panel on the door to reduce lf noise leak.
My riser was 2x12 with 3/4" plywood + 1/2" plywood + 3/4" plywood all glued and screwed. This time I'll make it a broadband base trap. So, I'll ue 2x8 on hangers for the internal part of the riser with 4x14 grills on the perimiter. It will be 10' deep with a slight curve inward and the full 17' 4" wide. It will be filled with Roxul Insulation.
It will be curved with a long curved step. It will be the same hight as the riser. I'll have a false wall. My screen is 11' 6" wide 2.40:1 with SMX Material. I have Paradigm Studio CC center and Paradim Studio v2 80's for LR. I have two Klipsch RW-12D subs.
I've read alot about acoustic treatments for this and I'm planning on going 2" on the entire front wall and enclosing the speakers to treat those.
I plan on putting in stained oak columns again and having my speakers in them behind acoustical fabric. I had Polk fxi A4 dipoles for my side and rear surrounds, but I am going to go with monopoles this time. They were filled with Roxul as well.
I plan on Wainscoting about 44" up and with some cut out in the trim framed with acoustic panels covered by fabric in them. The plan was to come out 1". I was then thinking about whether I would cover from the wainscotting to the ceiling in fabric between teh columns and put acoustic panels behind (ala Denis Erskine's beautiful designs) or if I would paint and put up some framed panels. I'm leaking toward the fabric over the entire wall betwen columns. Columns will be 22" wide and about 8-9" deep. The height of the wainscotting wood and above that wood perimeter but fabric inside.
Soffits: Soffits are filled with Roxul. They have 4" cans under them much like the theater I want to model and there is an extended shelf with crown molding and LED rope lighting in it on a Lutron dimmer.
I'll include some pictures of what it looks like now in aother post.
I'l also include a link to the theater I want to model the look after. The front will be similar except that the front will not have the wood panels below the screen.
Other than the wainscoting, my theater prior to the flood was very similar to this one. I had curtains where the side door panels are but I like the door panels better.
