I have a pair of the 600 M's on a bookshelf and unfortunately they must be right up against the back wall. I understand that its preferable to have them a bit off the wall but that's just not possible. I've also heard that if they must be up against the wall it's a good idea to stuff foam into the rear port.
Questions: Is this a good idea? If yes, what type of foam is recommended?
