It's a cozy space...almost too cozy. Theatre room will be about 12' wide and 16' deep. There's a goofy bumpout in the back (where the door opens) that makes part of it more like 14.5 deep.
I want to do a very shallow false wall, but that takes my viewing distance down to about 10' by the time you account for the wall, screen wall, and seating. I'm shooting a 100" image. Really getting kinda cramped.
I ordered an AT(acoustically transparent) screen in prep for a screen wall, so it's a shame to just hang that and not use it. But initially I just might throw my X-voce on a stand and stick my X-statiks in there and hang the AT screen on the wall.
After I get a little more money recovered I might do a baffle wall and build out 4"-6" and hang some inwall speakers in dedicated, treated cabinet space in that area. Treat around them with mineral wool, and then cover them with screen & AT fabric. That is sort of a hybrid inwall/false wall build where I give up 6" of space instead of 24" or more but still get a lot better sound quality and no rear wall noise loss from going true inwall with them.
Sounds ticky tack trying free up 18" of space...but it all adds up. I already lost 4" of space with the double drywall and resilient channel. Give up another 24" and that's almost 1/5 of my viewing distance.
I'm only going to have one row of seating. Initially it'll be a reclining couch (because it's paid for) but eventually I'll throw in some true theatre seating. Probably something like the Berkline Academy's that are a very narrow profile chair. Will be able to squeeze 4 of them in. It won't be ideal or pass any fire codes for hallway clearance...but it'll work for me.
