Thank you.....6 inch it is.from bigbassman aka Loyd Lowry:
1 4" aero is equal to 12.69^2in. so you can basically get away with 50% of a slot port with the aero port. this is also supported by other members like djman37. his testing shows 50-60%.
so considering 1 6" aero is equal to 28.27^2in (which would be equal to 56.5^2in which would be good enough for a 4 cube box) you can use 1 6" aero port for that sub and be fine.
