I could probably move the ceiling cloud back as far as I like. There will be no direct overhead lighting to compete with for space/shadows. I just have to ensure the position wont conflict with the tentative locations of future ATMOS speakers.

I plan on building the room and placing the speakers before the front wall is built. This way I can adjust and cheat the false wall forward or back as needed. Everything is precalculated to be pretty darn close already so far as I can figure. The program I am using makes it hard to triangulate the ceiling FRP with any accuracy. I have to draw it out on paper I think.

Increasing the spaces between slats is a good idea. I dont want to reject mid to high frequencies. I may also mitre the leading edge at 45 degrees to cheat a little more space in without being visible from the seating locations. Every little bit helps I guess.

See, I knew I wasn't done planning yet..... Will I ever be is the question. wink
