I'm adding a perforated screen to my theater room. The speakers will be enclosed in boxes behind the screen. I was advised to build the boxes approximately 3" larger than the speakers and then install a foam baffling material which apparently resembles egg carton bottoms. This material would be stuffed into all gaps on the sides, top and back of the speakers. Unfortunately, the person who advised I do this doesn't know the formal name for this product, which puts me at a bit of a disadvantage since I don't know how to order it. Anyone have any idea what he's talking about?
