Diffuser Wall

John: the wall at the rear of the pic (with opening for door) is the wall where we decided on diffusers. I am presuming that this wall will have resilient channel and double wallboard prior to installation of diffuser panels?? Correct?? Should the wall be filled with fiberglass or should it be empty?? Geoff

Yes it must have insulation as part of the wall isolation - the addition of diffusion is a separate issue and pertains to the internal acoustic treatment. cheers john
