Here is the room, almost perfectly to scale (1 grid square = 6 inches).

-Room is 12'x20' with ~7.5' (91 inch) ceiling height
-MLP is 9.5' from front wall
-Circles are in-ceiling
-Side surrounds are 3' behind MLP
-Rear surrounds are 10.5' behind MLP
-Surround Left speaker is as far forward as I can get it.
-Surround Right speaker could be moved forward a touch, but I figured it better to stay symmetrical.
