I think it has a lot to do with the type of music I prefer, room size, speaker size and maker as to where the speakers sound best. I mostly listen to jazz, blues and rock so my speaker placement is more immediate with an open sound stage that has more width than depth. If I listen more to classical, big band and or parade type music I think I would want a much deeper and wider sound stage because of the size and scale of the music and the complexity is much more involved.
I can also turn my bass cabinet forward or backwards and again for the type of music I listen to I have them forward.
My room size taking away the record rack along the back wall is 19D X 14'7"W X 8'H. I sit 3' from the back wall and 11' from my speaker. The speaker are 2' 8" from the side wall, 4'5" from the back wall and they are 9' apart at the tweeter. I toe them in quite a bit.
