George, obviously I didnt know that and now knowing that and sitting here in my office I am feeling this urge to get outta here and go redo the calibration. I have assumed (please tell me if I am wrong) that when you tell a speaker with side firing woofers like the 8000 its location, say left front, that it knows its right side is facing a wall and it will do some attenuation to the drivers on that side. I further figured that a setting like corner simply builds upon this realization that you are shooting into a corner so its stronger than boundary. I must find some time now to go and check out the settings. I might as well explore sub1 & 2 also while Im at it. Maybe that is more attuned to the lower frequencies?

best regards,
Jerry
