Not sure if this was the right place to post, but I thought I'd be more likely to get a response here... Anyway, I was thinking of changing my rears to the MS Premier 302 satellites, but the problem is that the listening position is back up against the wall the speakers need to be mounted on. Ideally I'd like the speakers to be pointed at each other and slightly down. Do the mounting brackets allow for that kind of angle? How much side to side and up and down movements do they allow?
