Thanks for the replies!
@trancemitr - yeah, one of the first things I did was contact Ted - very insightful, helpful, and patient. I'll be placing my order first thing Monday. I know the wall adjacent to the foundation is already decoupled but forgot to ask Ted whether it requires the DD and GG.
@Dennis Erskine - after drywalling, the narrower part of the room will be 9' 11", and the wider will be 11' 11" (the 12.5' was without the double wall). Wow that's a lot of screen width to sacrifice!
....if you frame that out as a straight wall, you can use that space as a pressure absorber for bass frequencies (and, for the record, that window is a "bass trap" all by it's lonesome).
The first half sounds like a good thing, the part in parentheses not so much. Would you please elaborate on the latter?
@fcaico - if I choose to keep the one wall staggered, i will for sure frame and block the window.
@HopefulFred - I'll be giving your build thread a read; thanks...also appreciate the info on space behind the screen. Thanks!
I'll have to research more into Dennis's suggestion. I like the idea of making it functional (hence the equipment rack) but never considered using it for AT.
Here's some more info on the room that I didn't include in the original post:
- I have an I-beam almost bisecting the room width-wise which 'll be framing around; given that I want to build a soffit for hvac and rope lighting means I'll have 2 soffits half the size as opposed to one continuous around the perimeter. Will this have a negative effect on the sound? What implications, if any, will this have on the venting? Aesthetically, I'm having difficulty picturing what it will look like, but honestly I don't think I'll mind if the performance of the room is not affected
- I'm aiming for 2 rows of seating (either 3/2 or 2/2; front/back) with the back row on a riser. I'm going to try and decide on a size of screen, so I can start calculating viewing distances and riser heights, etc. Or should this wait for a later stage?
Edit: I forgot to mention that the distance from the left wall to the point where the room narrows is 13 feet.
