i used two 4'X2'X.750" and two 4'X2'X.500" sheets to make the box. i had left over wood after all the cutting was done. i glued the two .500" sheets together to make the 1.000" front baffle. everything worked out great. hell, i even routered the begining edge of the port inside the box to get that nice rounded edge. i also used t-nuts for mounting the sub so there will be no stripped out screw holes.

now did you read the title of this thread?

i have no clue. i built the box to jl specs and it is what it is. now i started this thread to find out what port tuning is. since i built the box the way they wanted i assume it's tuned to 32hz.
