Just got the samples from Stretch Shapes and done some tests with my projector and Sound Level Meter and the results just blow me away. No difference about the gain, the image was exactly the same compare to my Da-Lite screen and the 2-ply white with black backing stop the light from going through the fabric, gain of 1,08. The sound did go through the fabric with a loss of 0,1db, almost nothing...
