Hello, I plan on building my first theater room and I decided to go with Klipsch Premier speakers. In the room I will be setting up in I only have a drop top to work with. I was looking at mounting 8” speakers for Atmos and came across the Klipsch ME-800-C speaker cut out. Would these work for drop grids or would I need to look for another route. Above the drop ceilings the studs arch up at an angle since it was a converted garage.
