[QUOTE="Timber_MG, post: 12980, member: 18"] The favoured stuffing isn't foam but plyester stuffing as encountered in duvets. just for reference: Havign some stuffing in the middle of the enclosure is much, much more effective that stapling some to the enclosure wall. Has to do with the fact, that at the boundaries of an enclosure the acoustical wave is a pressure maximum and a velocity null, damping (simplified) in a volume depends on resistance and velocity, which exists in the inner of an enclosure and not on its boundaries.
