Ciro71- Was playing with placement last night, and wanted to give you a more accurate placement suggestion. I am set up very close to the owners manual guidelines. My room is 148" wide. The O/96's are on that wall. They are 31" from the side walls, and thus 86" (7+ ft) apart.
As far as length goes, I am pretty spot on to the manual. My long wall is 279". I am 1/5th (56") out from the rear wall. My seating position is 1/3 (93") from the wall BEHIND the listener.
I can't tell you for sure on toe in, but I do like a slight toe in. I would just experiment as per the owners manual there. I always mark my previous spot with blue tape though. I tend not to fiddle alot with placement in general. Certainly not to the extent I did with previous speakers. Hope this helps !
