I am considering turning this room around. Instead of having the screen immediately on the right as you enter the room, the riser would be straight ahead with a 3' path to the left and the screen would be on the far left wall (so basically just turn the inside of the room around 180 degrees and make some riser changes.
This would lessen the quality of the rear seats. If I stick with 4, one would be against the wall opposite the door, and the quad would be off-center in the room.
What this would buy me might make that worth while though. First off, there would be more wall-space as you enter the room for controls/switches. The front stage in the current design only has about 28" of depth for an 18" speaker. If I want to frame the screen with a nice pro-scenium (I think that's the right term), then the speakers will also have to be flush with the side walls. I think I've read you want about 3' between the side walls and the front mains. With the design change, I'd have about 3' behind the screen. I could actually move things around much more as there are no doors that limit what I can do with the front stage. The other benefit to the design change is that the A/V cabinet would be in the rear of the seating instead of up front by the screen.
I prefer the "walk into the big open part of the room" feel I've got with the current design, but the positives are starting to seem like they outweigh the negatives.
Input is welcome. I will try to post an updated screenshot of the design this evening.
