3.5 ft^2 each @ 40hz after displacements will be nice. Mine sits in 4 @ 40hz but I could see it wanting a little smaller box for that extra umph up high.

well I can come up with 6cf net but only have 85.5 sq in. of port with a leangth of 15.5 and would need 96sq in of port so what size aero port would I need to make up the other 10.5 in. ? Also would I still have some bottom end down in the 30hz range?
