do one 4" aero port 13.82" long in 2.1 cubes and it shoud get ya about 32Hz still not alot of port area though

how much area would that be?

 

[pr-festiva 10+ year member]

12.56 but it would be with an aero port which would help a little

problem is your wanting to tune real low ,so the port length is going to be pretty long for larger then a 4 inch port
