Looking to add 6 2' x 4' 703 panels to my front wall.
The pics are of a corner mockup
What I want to do is take advantage of using the edges of the 703 panels for any extra sound that just might be bouncing around . . .
So the frame is outside dimension, 2' x 4'. and about 2"+ or 2 1/2 deep, and have 2 center braces at about 16" and 32" for stability/rigidity, and the roundover on the corner is 1/2"
I want to use that "standoff" from the wall as an absorption "enhancement", as I have read here can be of some benefit by not having the panel flat to the wall
so the 703 panel will rest on the 3/4 edge of the ply but I will also have an AT backing very sheer material panel stapled on first, for support and fiber controll
I have "modded" a plastic 3 way drywall corner piece and attached as shown, will give me a 1 7/8's depth at the four corners.
Then the whole thing gets painted , as needed, and wrapped in my finish AT fabric.
Because I have not so flat plaster walls, I will run a weatherproofing foam strip, 1/2" x 1/4" (thick) on the back 3/4 ply frame edge.
Then when it is set onto the wall using a french cleat, it will (HA! HA!) seal onto the wall, if ever so slightly and also provide some vibration damping against the LF in the roof.
all in all not so different from how most approach this as part of the solution, "What about the Room?"
