Am I misunderstanding your question?
It almost reads to me as if you are wondering about using one of the corners of your room as the back drop for the speakers versus one of the flat walls being the back plane for your speakers?
System set up in front of corner Vs flat wall - acoustical issues?
The room size is about 22 x 16 and because of lay out I'm considering having a corner of room be the backdrop of the system. It's a combo home theater/ two channel listening environment.
Each shorter side of the room has either a window or a French door exit, so it's difficult to put the system along the shorter walls which would be a lot better. Putting system in the middle of the longer wall presents a challenge for seating environment. Too much space on each side of this rectangle room.
I haven't seen any systems with main speakers set in front of a corner. It would seem to be a more comfortable layout but I wonder what the acoustical challenges might be.
