I'm seat at right and my girlfriend at left, I figure to set the mic between us for the first test. My sub is on my 2 rear corners about a feet from corners, the physical distance is 7' from sub to the middle of the loveseat. I place the mic about 2' away from the first position to the others 7 positions ,I don't remember exactly the pattern but i did what audyssey told me, the 1,2,3 position was on seat 4,5,6 at feet 7,8 behind the seat .
