Hi,

I've never heard of anyone advising calibration at the room's dead center. It makes no sense unless you sit there. Given the vagaries of standing waves, you could calibrate there and then find the subwoofer balance would be totally wonky at your seating location. Not to mention the settings for the surround levels and left and right mains. Technically, if there's a couch, you should calibrate for each seating position along the length of the couch, average the settings. . and ..You see what I mean?

Calibrate only at your seating position and hope the sound is reasonably consistent for other locations. It usually is if the room or setup isn't too eccentric.
