Hey John - I already tried that, appears you ALSO missed the part about his wife, sleep, etc - it wasn't too clear at first that the only way it sounded good was keeping his wife awake... Steve

Gettin to the details
Guys,
Tired, day started @ 4:00 am, just now got home. Yes it is a style of quansut hut but with a better shape. I looked @ your drawings with the inside sheetrock isolated from outer studs with some kind of steel offset piece. I like the way that works. Doable. I propose that when I get time I will go down to the shop & get the actual dim. of what the inside room would be using this construction method. A couple of ques. Are you saying I should stay away from using cedar on the inside? Just go with sheetrock? Also I would have to put a final layer of something besides sheetrock on the very outside, the shop is not heated, so I'm afraid the cold, & humidity would destroy the sheetrock rather quickly. Where can I find info out about this steel you are showing to isolate the inner sheetrock? So I can work up the correct dim. for you. Gotta hit the hay, thanks guys. fitter

Fitter, you can still use your cedar inside - you might want to build some slat absorbers in there to keep things bright and still lessen modal characteristics of the room - the cedar would be perfect for that.
As to the outside sheet rock, there's nothing saying you can't use OSB, T1-11, or even greenboard - just no air gaps except the one between the inner and outer leaves.
I've included another detail on the sway bracket showing more info. This bracket can also be used on the end of a longer 2x4 if you want wider air gaps between inner and outer wall frames. I've not yet drawn that scenario, but if it's necessary I will when I get time. The basic concept can be used to isolate either wood or steel framing with nearly any spacing. These types of brackets if bought readymade will run anywhere from $40 to $60 each, so someone who's handy with tools can save quite a bit by fabbing them.
If by "steel isolating the inner sheet rock" you're referring to the Resilient Channel the rock is hung on, that's a commercially available item - usually found at commercial drywall places but usually NOT found at Home Depot (although some HD's do carry it) -
One of the better versions -

Dietrich's RC Deluxe is the recommended one from them, the double leg stuff doesn't isolate as well, and the standard stuff isn't recommended for ceiling use.
There are other sources of RC, depending on your area - some places it's harder to find than others. Basically, all of it stands off wallboard by 1/2" away from the studs. When you fasten wallboard to it, you need to be sure you don't put any screws where the studs are because just one screw will wipe out most of the gain in sound isolation the RC gives.
Anyway, gettin' late for me too, here's that other detail... Steve

Room dim.
Hi guys,
Sorry it took so long to respond. I have worked some long hrs, we lost power at home, & had some terrible weather here. And the real truth is sometimes I just get lazy.
Anyway I went down to the shop & got good dim. If I put rc on the inside studs, & hang sheetrock my final dim. will be, W. 121.25" X L. 181.625" X H. 90.375". Would these dim. be condusive to getting a good sound? Thanks in advance, fitter
P.S. About the height dim. This measurment was from concrete floor to ceiling. I would like to put in a wood floor but not know exactly how to do it, so this dim. will change (gonna make for a short ceiling). Also I did not include the dim. change for angling the walls in 6 degrees on the sides as suggested. One more thing where should amp placement be? On the end with narrow sides, or @ the end with the wide sides? Thanks

Fitter, I know what you mean about all the "fun" life dishes out - I'm off to my last 12-hour graveyard shift in a few minutes, then off for a few days (in which time I only have a few MONTHS of stuff that needs doing, like cleaning up all the broken limbs/foliage from the ice storm we just got through...
I'll get back to this probably tomorrow afternoon, when I've got time to give it a more thorough answer... Steve
