When used with a 1080P projector, this surface produces optimal sound. The special weave, inherent in its construction, permits the sound to come through while blocking unwanted ambient light. The numbers bear this out: damping at 20kHz only 2dB and the Max. Attenuation at 20cm is around 1dB. The detachable black backing for fixed frame models is convenient for cleaning and storage. The image produced by this surface is both clear and true.Size and Aspect Ratio
