do you want spl, SQ, or a mix of both?
20's for sq
30's for sql
40's for spl

JL reccomends 33.7 Hz, is that good for a mixture of both?

It's a function of the port's cross-sectional area and length in relation to the size of the box; http://www.jlaudio.com/tutorials/ports/index.html


Or you can download a program like WinISD, and when you input the box size and port diameter (or lenght and width), it will tell you how long the port has to be for a desired tuning frequency. However, WinISD and doing it using the forumla almost always give different lengths needed. Best to do it by hand IMO.
