I'm just about to make the purchase of more OC703. My front wall has a lot of broadband 703 absorption, but I have a new idea. I'm going to make the front wall 12" thick. It will be: 4" OC703 2" air spacer 4" OC703 2" air spacer Wall
From my reading, you get extra benefit from an airspace as long as it is not more than equal to the thickness of the absorption. In my case it would be only half. Yes, I could make the 730 solid for 12" but I'm not sure if I gain anything. I watched all of Eric Valentines videos. I know he got his room responding as he wanted. I'm not completely convinced the Tube Traps were any better than using OC703. It's basically the same thing. Does it really make a difference that it is round instead of a flat penel? I'm not sure. The OC703 lowers the velocity of sound waves, drom what I understand. Having a foot thick wall of it may be even better than Tube Traps. My room at the mix position works well but I still have a couple issues 100hz and down. I think this might solve it. Next, I'd need to figure out a clever way to make the panels. I've basically used the GIK design for some panels in the studio, along with some real GIK panels. That's fine for 4" thick, but once I get to 12", I think I need a better design, so they stack well and easy.

I just placed the order with ATS for another 24 panels of 4" thick OC703. The front wall will now be solid OC703, 12" deep plus an air gap behind it and maybe I will place a spacer between panels. This way I will end up with 15" deep panels. If it smooths out the low end just a little more, I will be happy.

You’d get better absorption with 4 inches of GFR 5,000 material in front of 8 inches of 703 versus 12 inches of 703. I went with Caruso isobond to do this very thing and they’re sold in the same size panels as 703. The attached picture shows the difference Attachments:
