Any updates I should be aware of since the original post? The material doesn't look like it's available anymore, what is everyone using? Interested in reducing reflections off concrete and drywall walls.
Frame construction still the same or is there a new preferred method?
If you want to use any movie poster style or images with characters on them, then you should go to MyFabricDesigns and look at their Basic Combed Cotton.
If not, you also have the choice of Spoonflower and using Silky Faille (their Performance Knit that was so good is no longer available, but this is still great fabric for quality).
Frames are pretty much the same as always.
I am still partial to the tried and true OC703, but there are other choices out there that work very similarly.
I wasn't able to buy anything locally when I did my acoustical treatments over the years, so I had to buy online. I picked ATS Acoustics, but I am sure that there are others. They do have a list of the products that they sell and let you compare them to OC703.
ATS Acoustics Insulation Comparison
Best bang for your buck is 2" of rigid insulation and then put an air gap between the insulation and the wall. So if you used a frame that was 2" thick, you would put the insulation at the front face of the panel (closest to the fabric) and automatically have a 2" air gap between it and the wall. Studies and tests were done years ago that show a 2" sheet of OC703 plus a 2" air gap behind it performs almost as well as a 4" sheet of OC703, but for half the cost (since the air is free).
