Nah. Planning isn't the problem; it's the outside forces that are the problem.
If you later on decide you need soundproofing, will it be more expensive to do? I'd think it would be more trouble at least, since the room would be set up fully at that point and have to be taken apart. Still, if you decide you can get away without it and do just the minor things you mentioned, then that's money saved.
Since the rec room will be finished already, the only added expense for soundproofing later would be rebuilding the screen-wall if I do the screen-wall route. There's also another screenwall option I've designed and may get custom built. Going that route would make a later sound-proofing effort quite difficult. Maybe I should stop posting my soundproofing ideas, only because they change EVERY DAY!!!...Nahhh. lol. Soundproofing has the fiscal blessing of the Mrs. so it really is all up to me.
Yeah bro, I hear there's a guy in TN that's the best in the business!
I don't know how you did the measurements/calculations, but soundproofing shouldn't require 2 feet of wall thickness on any wall. If you use staggered studs, you only add a couple of inches. Even if you use a double wall with double layers of 5/8" drywall, you wouldn't be adding more than 6 inches:
I'm just sayin'...
My estimates were based on some pics I saw in Vikrao's build thread. The wall's cross-section looked to be just over a foot or so, and I'd be adding OSB to the mix, as well as 2-inch and 4-inch acoustical panels all around, So I estimated nearly 2 feet in width. Probably closer to a foot and a half though. I was leaning more toward the double wall instead of the staggered studs since I should, in theory, be able to build the second interior wall without ripping down the drywall on the original wall...but with staggered studs, the width of the studs overlap with the original studs. How would the new decoupled ceiling joists rest on them, without touching the tops of the original studs? If I can do staggered studs and only lose a few inches, then I'd definitely look to making the 11x27 room the theater, instead of the main rec room area. Plus, the 11x27 room comes unfinished.
Edit: Found the answer to the joist question: IB3 clips. Also found out that I can't build the room within the finished room due to the triple-leaf effect. Looks like staggered studs are now definitely the most desirable option.
