That's just what my guy said we should do. I sent him pics of yours. Our ceilings are basement ceilings. 7.5'. So we can't go as low as you have mounted yours. I sent him photos of yours so we can see what we plan on attempting one day.
So JUST molding nailed to the wall? Did you "block" it out to give more room? How tall are your ceilings?
This is what I want to do in our theater but leave room for running speaker cables also.
