I want to this heavy bookshelf speaker on my ceiling as a center-channel, preferably horizontally, as it's above my projection screen. I want to angle it roughly 20 degrees downward so that it's properly aimed at a listener sitting on a couch about ten feet away. It's 11 x 8.2 x 14.8 inches ; 16.1 pounds.
It has no bracket mounting holes, and I'd prefer not to screw into the cabinet, but will do so if necessary. Wall mounted brackets are not going to work, because the screen is in front of a bay window.
