OK, Did a little measuring. As long as the person playing in position 3 or 4 is not overly big or long forearmed, you can fit at a minimum width of about 16 inches on each side. So I think a Gauntlet cab body is roughly 28 - 29 inches wide, so that would bring the total needed width to about 60 inches to play. For maximum comfort, 20" on each side would be great, and if you got some hefty players, 25" should fit just about any person.
