Box dimensions 37W, 17H, 19D. slot port 15.5" high by 4" wide. 29" of port length. you've got yourself about 4.3 cubic feet net tuned to about 33 hz.

i know these demensions would plug in a little off, but they are exact and correct for that specific sub. 5'^3 internal @ 37x17x19 -port displacement. 33hz port @ 3.25w x15.5t x 15"deep. guaranteed to hit real hard all the way down.

well, just remember, if you have a 2nd gen, l-7 (with the 8 cone webs, not 4-way brace) be real careful of bottoming out under 30hz, and turn it up slowly watching.... more-so with the larger port recommended earlier. gen 1's are less prone.
