fdelin's theater plans - Currently Fabric Wall dillema

**fdelin** · **11-05-09, 11:58 AM**

OK, Here's a quick drawing of near and far walls, the front and rear are pretty trivial. I think the panels will actually be 51" wide, not quite golden ratio but quite close. It is however, 48" + 2 by 1.5" for framed panels. The gold lines are just a thought, maybe some kind of accent, maybe a chair rail, not sure. Hmm, OK, quick edit with some extra math, If I do the bottom panel in a side ways golden ratio I get a rectangle, 32" by 51" if I do a 2" detail there I get a 51" by 51" square on top which should both be visually appealing and work out to the same 48" + 2 by 1.5" size with frame. So 3 and a quarter pieces of 703 per panel. Still puts me at a weird 42 panels required, I guess I can use the odd ones out when It comes time to make bass traps/soffit trim/etc....

The hvac ducts being behind the false wall won't be an issue. The false wall would be just studs and acoustically transparent cloth. Air will freely pass through it.

Or...

you could make your side elevations look something along these lines...

Just for your reference, there are no "golden" rules regarding panel dimensions.

Is that wood paneling? Isn't it reflective?

Bryan, can I put 703 in the 2x4s framing the front wall or does it need to go on top of it?

It is reflective and it is also absorptive (depends on how thick and what type the wood is

), but are we all that concerned with reflectivity below a chair rail? To some degree yes, but mostly no. Don't take the above drawing to scale nor as a true room. It was not intended to be that way. All it is depicting is some ideas. No sound aspects of sound analysis was done for this room.

No sure what you are quire asking here, but if you plan to permanantly enclose 703 inside of a wall, I would not do it. If it gets wet, it will cause mold to grow. Good luck!

If you mean don't drywall the front wall, that will impact isolation severly. Doing it on top of the drywall is a better solution.

You can do some wood on the bottom but not with 4" or so of ear level. Some folks make the inlays cloth and just strips of trim to frame it.

Bryan is correct. Don't take my drawing to scale as it isn't. It is just intended for interior ideas. I give you the cart, but not necessarily the horse.

No, I'm not drywalling the wall I framed(almost done) so I can still access the window if need be. It's only 1 and a half inches from the wall behind it. I was just wondering if I could put the 703 between the studs to keep the fabric frames I'm going to put in front as narrow as possible. I'm nailing a 2 foot wide by 1 foot high, 1 and 3/4 inch thick piece of plywood to the front of the framed wall on which to put the mount for my plasma. It's a low profile mount so I'm just trying to give the set as much room behind to breathe as possible.

I you're not doing drywall then sure, put it in the stud cavities. Just understand that there will be a huge loss of isolation into and out of the room as they sound will flank right through and up/down.

Another option could be to drywall and just make a panel that's removable with thumbscrews when access to the window is required.
