The brackets will not grip the speaker tight enough even with double sided tape. Actually, the tape grips but it is not nearly as secure as I would want it to be if I were going to angle the speakers downward. That sucks! Anyway, thanks for responding guys, and let me know if you have any other ideas.
Also, do these speakers need to be mounted into a wall stud? Since they are 12 lbs. I am assuming you can easily secure them to any wall with anchors? Thoughts?
