Micah, I'm surprised a few others don't have a similar story as yours(maybe we just haven't heard them yet). When I got my QS8s I knew the first time I went to hang them on the T-bracket that they would need to be "seated" solidly into said bracket to avoid a possible catastrophy...broken speaker or FOOT! anyway, I had a bit of trouble getting the brackets to line up and lock properly, so I just opened up the lip on the brackets to "guide" them together...so much easier then continually trying to hook the bracket, missing it and potentially dropping the speaker. I know a few others have bent the tab out a little on the bracket tabs to help them connect, it really does help to join the two halves of the bracket. Once it's connected, I gave it a little tug(no jokes please) downwards to make sure the speaker was fully seated.

Half of communication is listening. You can't listen with your mouth.
