Hi all,
My control room is 14 x 11’ and I’m wondering about final treatments. I already have corner slot absorbers in the two front corners and I’m wondering about details for the back wall. John has been a big help and told me basically in a room this size, my best bet is to use a completely absorptive back wall perhaps with an angle downward.
I have also read Ethan’s comments about bass traps on the back walls. I’m a little confused which way to go. I was going to use 2” 2x4 OC 703 wrapped in burlap and fit into some wood frames. But I’m wondering if that’s enough for the back wall. Has anyone done something like this in a room of this size ? I there anything you would do different ? Should I be thinking about deeper bass traps ? If so, are 4" traps going to do the trick. I don't want to lose any more room.

The Idea is to lift the treatment off of the wall which enhances bass trapping/absorption. Anywhere from 4 to 12" is cool without losing a lot of room real estate.
Johns DIY bass traps take the insulation about 6" off the wall. So I trust his judgment there.
You want to absorb the rear wall in a room that small to reduce/eliminate reflections off that wall phase cancelling what is coming off your monitors and smearing your image.
The 2" 703 is cool, just lift it off that wall. I went with 4" Semi-Rigid Rockwool myself for my room. Just preferred the coefficients better.
