I originally posted this in the DIY Acoustic Treatment thread, but as it has been inactive for a long time, I don't believe many people saw it. I am posting it here hoping to get some feedback as to any shortcomings there might be in my design...
I have read a lot of the posts on the AT Master thread and since I am not an engineer or really an audiophile, much of what is "discussed" here goes over my head. I think I have picked up the basics and would like some feedback on my plan.
I have an oddly shaped room and hope to improve the basic acoustics by placing some panels in the places usually suggested for calming first reflections and by building some corner base traps.
I am trying to come up with a simple construction plan using OC703 spray glued to some 1/4" plywood with significant cutouts to allow the sound to penetrate through to the void between the back of the OC703 and the wall. All of the edges, front and rear would have drywall corner bead on them to allow for an attractive and impact resistant corner to the acoustically transparent fabric covering for the front and all the sides.
I am not much of an artist, but here is a sketch of what I am thinking of doing:
So, the OC703 would have minimal plywood between it and the space behind it. The sides behind the absorbent material would be as open as possible yet covered with the cloth covering and the edges would be protected by the corner bead. In order to maximize the benefit of the absorber the sides would not be covered by a reflective wooden frame.
Am I headed the correct direction? From what I have read and the examples I have seen, I think so. BUT...I have been known to be pretty thick sometime.
Thanks for your patience.
