Screen wall acoustics
My theater has been "finished" for a few years, just getting a few small adjustments and improvements from time to time. One of the things that always bothered me is that my screen wall, which is a 100% acoustically-transparent combination of an AT screen and GOM panels, allows you to see the through the GOM to the speaker stands and cabling when I have the Imax lights on. I decided this past weekend that I need to do something about that.
The obvious choice is to back the GOM panels with some sort of opaque cloth. After a quick trip to the fabric store I came to the conclusion that I'm not going to find a cloth that is both AT and opaque enough to achieve my desired result. The best option seems to be a velour or velvet, similar to what I used to cover the masking panels.
The question is whether adding this less-than-AT material around the edges of the screen is going to have a significant effect on acoustics. If so, then what are my alternatives?
Compared to other screen wall designs, my wall has a lot of screen surface area and very little panel area, so the % of wall that will change is relatively small. You can see the layout of the screen wall and speakers on page 3 of my build thread linked below. And the finished wall is on page 4.
Any thoughts on whether or not I'll be OK with my current plan?
