floor to ceiling axial modes about 64 HZ 128, 192 etc..
tangential including the eight about 72hz 136 201, or 81 , 140, 204... etc
I'm using 4" insulation for the clouds, how many inces from the ceiling will work best ?
and... a mebrane in front of the insulation or similar tricks for the lowest modes?
P.S. walls/ceiling corners are chunked already..
