Does anyone have suggestions ceiling diffusion treatments with a very low profile? My basement room has only 7-ft (2.1 m) height. With a higher ceiling, I'd use skyline"-type diffusers, but I am hoping to find something with less than 2 inches thick.
Apparently the
Diffuse Signature system might work for this. Last time I checked, it was extremely costly, and I wonder if people know of good alternatives.
I'd prefer to avoid anything with significant absorption. The carpet on the room's floor (long story) deadens it enough.
And ideally, I'd like to avoid gluing anything to the ceiling.
Have my requirements ruled out everything by now?
