Are you planning some sort of frame around the whole thing ?

Originally I was planning on having a frame around it, but I kinda like it with the edges open. And this will be plenty strong enough once I get it fully assembled. I think I'll consider solid blocks for the end wells.
I forgot to add previously...the reason why these are only 3.5" deep, is because the right diffuser will be on the wall of an isle that people walk past. Even 3.5 inches sticks out pretty far.
If I redo my back wall, I'll probalby do 6-8" deep. This is what I have on the rear wall already:
It's a bunch of flutter breaker diffusers made from vintage oak and pine stair treads, with a pair of 2' X 4' MDF QRD in the middle. Both projects were blatantly stolen from other plans. I just scaled them to my needs, stained them, and screwed them to the wall on 2" X 2" furring strips. The airspace behind the diffusers was then stuffed with 2" rockwool acoustic fire blanket.
