This group helped me quite a bit 5 years ago when I was working on a 2 channel audio setup. I'm now working on building out a home theater space and trying to see what makes sense for my room in terms of speaker type and placement for Atmos.
A couple key notes:
1. This room is a work in progress, new media console is coming I do not plan on having my center channel block the TV long term, nor will I be keeping gear on the floor.
2. I am putting up acoustic panels, right now it looks like roughly 12 based on reflection points but I need to lock in some speaker placement to confirm
With that out of the way the big piece I'm trying to figure out is Atmos speakers and dealing with the ceiling drop pictured below. The ceiling is roughly 7 feet and the drop area is 6". As you can see that lines up right about where my mains are, my worry is putting in ceiling speakers just to the right of the drop. I can everything roughly a foot to the right, that would buy my more space to the right of that drop but more wondering if that will have a material impact on sound or not. This was me just thinking high school math, but if a speaker has a conical dispersion of 90 degrees and I placed it over 7in from the drop vast majority of the sound would not yet hit that vertical surface. I'm not an expert here though and that could easily be an oversimplification so I'd love this groups insight. What would be ideal for this space? My receiver will be capable of 7.4.2 but I think 5.4.2 makes more sense for this space as
