First of all, you linked me to the L5. Second of all, I have already looked at the T/S Parameters and the correct manual and none of them list either value. Also, google didn't help at all. Thanks bud, but next time, try to hold back your ego long enough to realize how ignorant and stupid you're being.
however while the displacement is not there the recomended port dimentions are in-fact THERE ON PAGE 3 so i appologize for wrong link but 1 half of what you asked for was there so just do a little math and put YOUR EGO BACK IN YOUR PANTS
SAYS 3.0FT^3 W/ PORT 2.5"X 16.5" MIN 6.0FT^3 W/ PORT 3.5 X 16.25"
so apparently kicker does not have a set sq in per cube reccomendation
but since your sooooo knowledgeable I'm sure you kno the average is 12-16 sq in per cube
