Hi, im building sub enclosure for 2 Orion hcca 15.2's, the website says that both subs should have 7 cubic feet....and tuned to 35 hertz i want to port it in the middle and i was wondering if someone could tell me the measurements i should make the port for both of the subs..

Same size.  6" port = 28.27 square inches of port area, so just make the opening equal to 28.27 sqin and the port length 4.5" long.  28.27 sqin = 2" X 14.135", for example.  Any geometry that equals the same opening area will do.
