I'd ask Marty Hart, he will know off the top of his head I bet.
I'll say that whenever you see a center aisle, it's often combined with a cylindrically curved ceiling. A ceiling configuration like that often causes
a flutter echo in the center of the room so you put an aisle down the bad sounding part instead of putting seats in it.
