Since I set-up my SVS Sub my QS8s' with the standard mounts have started jumping off the brackets. While it certainly adds to the movie "experience" it is probably not a good idea in the long run.... Anybody got an idea other than to switch to the optional mounts ? I'd hate to put more holes in the wall or they could come down next. I'm thinking of wrapping the bracket to the speaker over the tab (somehow) in the back... Anybody else suffer from this problem and solved it ? If not, a good test is to rent "Hellboy" and crank-it-up.....
