ssa xcon 18 port area

[raptor727]

building a box for my newly aquired xcon and need to know how much port area I need? thinking 7.5 cubes and for a port 4" wide and maybe around 18 or 19" high not too sure so figured I would ask for advice thanks for any help

oh and want to be tuned around 31hrtz maybe 30, thought 4" wide port sounded good if it's too much let me know

well came up with a 5" wide port 19.5" high and 26" deep tuned to 31.46, 7.77 net volume and 1.99sq ft of port area wich comes to 12.55 inches of port per foot sound good???? Anyone? lol

i can match this when i use 7.5 ft^3 rather than 7.77 ft^3

well thanks for the advice but i am going with the optimal ported specs on the website, the box is a little complicated but I imagine it will sound great
