Here is a close up of the corner where I am considering the right surround placement if I go with a 5.1 setup. It will have to be on the side of the vault because of my front door placement on the other side and I assume will need to be angled down (it will be hung around 8.5' off the ground).
Looking from where the TV will be. This is looking at the back wall where I am considering Rear Surrounds in a 7.1 setup.
This is the living room dimensions, where I will have a vaulted ceiling verses normal 8' ceiling, and approximate surrounds placements (black for 5.1 and the pink for 7.1).
This will be the shape of the living room when the room is complete
Approximately where the TV, VP150, and M22 v2's will be. From here you can see the vault height (13') and the lower ceiling section on the right (8')
This is an angle looking were the right surrounds might go. Black arrows are for 5.1 and Red arrows are for 7.1 placements.
Another angle to see where the right surrounds would go.
