I got an X con 12 in a flared horn box I got from the person I bought the sub with, he said it's not specifically tuned just made for wide range. The port starts at 1 forth the subs surface area and wraps around and ends at the same surface area, nice and tight bass up near 70hz which is weird this sub his dang hard from 50 to 38ish hz then not as much noise but still hella shaking with a hifonics 2000
