This "speaker" has nothing to do in connection to your tv. Although, it would look and sound nice... As long as the speaker system is hooked up to av receiver.
Now, if you want to mount the Bose cubes on the wall/ceiling...
You MUST use the UB-20 mounting bracket. Keep in mind... The brackets are sold individually, not as pairs. So it gets EXPENSIVE to mount nine of them...as I have :(~
