Studing the walls as I type.Room will be 20ftL X 8'6"H X 12' 3"W. Screen will be on 12' wall and rear wall corners are 3' 45 degree diagonals.( think of a bay Window)Door is 14" back of front wall.My question is what impact will the rear cut off corners have on the sound and what size system and best config for the speakers.Assume I want to do it Right.
Thanks Bjojns

If anything, those corners will help you since they will discourage standing waves from forming between that side of the room and that opposite one. Overall, though, it depends on many factors:
the furniture in the room
the location of the speakers in relation to all the surfaces in the room
carpet or no carpet
etc.

Peter, in theory that might make sense, in actuality this isn't true. According to Rives Audio, having 45 degree angles in your room is not your friend. Instead of eliminating standing waves, it just makes them harder to pinpoint and treat. 90 degree angles are much easier to treat for standing waves than 45 degree angles. Exactly how are you supposed to put up a bass trap on a 45 degree angle?
My suggestion, instead of having 45 degree angle corners, frame in 90 degree, and put in bass traps to give you the 45 degree angle look if this is what you desire. And you room with sound awesome.

How does a standing wave form on a 45-degree wall when there is no parallel surface opposite from it?

Standing waves result from reflections. Non-parallel surfaces still result in reflections...albeit reduced ones. And following up on Robb's point, standing waves from non-parallel surfaces become harder to control because the geometry makes the math more difficult.
