Im trying to balance accoustics with asthetics and was planning on hiding my speakers behind fabric panels. Originally I was just going to go with the thin black speaker cloth but now Id like to match these panels with the heavier fabric I have in panels all along the walls. Will a single layer of it substantially muffle the sound coming from the front L & R? I know it's going to muffle it somewhat, but Id REALLY like to use the decorative Victorianish fabric to match the rest of the room.
