Well I officially have a nice mix of everything
What would be the best way to approach this? My screen length
will depend on front speaker placement, as will my false wall dimensions
. I don't want to build the wall and order the screen only to find out the only way to fix things for good sound is to move the speakers to dead center of the screens frame, or false wall frame.
Any advice is appreciated - Bear with me as I explain in detail my rooms details
My L/C/R and screen (AT) is on a wall that is sheet rock>2x4>insulation>inch of space>concrete. This is only the bottom 45" of the wall. 57" above is set 8.75" back (simply put I have a ledge 45" off the floor) sheet rock> some headers, some 2x4 framing>insulation, windows x 3.
Facing the LP the left wall (15' long x 8'6" high) is mostly sheet rock>2x4>sheet rock (interior wall) with the exception of the first (from screen/front speaker wall) approximately 30" which is the same sheet rock>2x4>insulation>inch of space>concrete (simply put I have a 30" foundation intrusion on my left wall) I planned to strip this part of the foundation down to the cement to get closer to the majority of width of the rest of the wall.
My right wall is the same as the screen/front speaker wall from 45" - sheet rock>2x4>insulation>inch of space>concrete. Above 45" is the same ledge but the 57" above is sheet rock> 2x4>insulation>plywood>weather wrap>cedar siding (exterior wall) To make it better there's a 2' deep by 3'7" wide alcove. 45" is foundation and 57" is exterior wall.
My back wall is an interior wall so sheet rock>2x4>sheet rock
Here is a picture of the wall my front stage is going on. You can see the intrusion of the foundation on the right side of the picture. The most I can do with that intrusion is get rid of the 2x4 framing and insulation making it only stick out approximately 5" with no sheet rock on it.
Also attached is a sketch to scale, so you can see the alcove area.
