What would be an optimal Hz to tune/build a ported box to for a JLw7 for MAX amount ofSPL I can get out of it?

I know its an SQ sub but im not concerned with SQ one bit! Im lookin for as much hard hittin SPL as I can get out of it since I already bought it n maybe I can make myself a lil happier with it..so with that being said can someone tell me what the optimal/best amount of cubic ft box I shuld build as well as total port length and how wife the por shuld be please. I want to do an L-shaped port chz im good at building them that way. Would realy appreciate if sum1 culd help me with this bcuz I have no access to a bixbuilding program (bad signal on laptop and cant get on on my fone either) PLEASE HELP! Thanx so much in advance.
