Building acoustic panels. How to get frames flat/square?

I built a few acoustic panel frames and they came out really good. Only thing is when you lay them flat on the ground, they don't lay flat. One corner is sticking up in the air a bit. I even used L support brackets. I'm concerned that the panels aren't going to look flush on the wall or that they may wobble. I've seen people use a brace through the middle of the frame but that only seems like it would help the wood from bowing in from tight fabric. You think if I make some triangle braces and put them on each corner on the back of the frames would help? Here's what I have so far!

Anything you do in the way of a "knee brace" [diagonal at the corners]will only be more of an attempt to square the frame up but will not remove the warping that is either from the thin wood material or the pressure the cloth material is applying to the frame. Several ways to do it. Either use thicker material Or attache a hard panel plywood over the frame OR install the absorber with french cleats top and bottom to secure the panel to eliminate the twist. Certainly there may be a few other options, but these come to me off the top of my head.:)
Wow. :shock: That's actually a great idea. I've never heard of those before, but just looked them up on YouTube. Looks like it will completely solve the problem as long as I can find ones that are as low profile as the ones in this vid: http://www.youtube.com/watch?v=VCndB5kX ...
