Room damping for Magnepans
I'm trying to find a less expensive alternative to purchasing dedicated damping panels to place behind a pair of MG12 Maggies. The room is less than ideal (it's small and full of gear), so I have to move the speakers closer to the back wall than I would like and they don't seem to like that. Commercial panels are expensive and don't really come in the right size for this. I also wanted to come up with something that doesn't look cheap and half-finished like egg crates or pillow-filling. So what are my options?
Also, the Magnepan manual recommends damping behind the center channel (an MMG-C on a shelf under the TV). Any suggestions for what to use there?
