"The imaging is fine in my seat, but it quickly goes away if I move over a couple feet" .......sitting 8 feet away from the screen,your speakers 11 feet apart and toed in sounds like you will have a very narrow sweet spot ,i would suggest getting the front mains as close to the tv as possible ,and take off some of the toe in as needed,then slowly work them further apart until you found a happy medium for the seating area....ron
