In this home theater, the ceiling was lowered to completely hide the projector in a false ceiling. It should be dust-protected and tidy. All other devices, cables, and connections are of course also hidden. The drywall was clad with corner protection strips and installed directly under the lift.
Soft dimmed lighting, high-quality devices now bring the ultimate home theater feeling. Only the popcorn is missing. That's the only thing not built into the ceiling.
Well done!
