I use port length calculators online, just google it, type in the internal box volume, the size of your port and the tuning frequency that you want. If I wanted an spl box I'd probably tune a bit higher like in the 50+hz region, but I'm an SQL guy so I like to stay in the low 30's. Never built an spl box before though so take advice from people who have.
