I have been using the 522d-SSs as the rear channels in a 5.1 system mounted flush on the wall. I just moved and beginning re-installation when i discovered that one of the walls that i was going to mount on is made of some sort of metal. The ceiling is concrete, so that's really not an option. I was thinking of getting speaker stands, but i was hoping to find one tall enough to put the speakers at the appropriate height (6 ft?) I don't even know if that exists or how i would monthe the speaker to the stand. anyone with suggestions?
