Tuning frequency is a function of box volume, port area, and port length. So once you know what volume you want the box to be, add the port to it to get it tuned to what frequency you want (must add port and sub volume displacement to the overall size of the box). You can use the port calculator on this site to help you out, or I use winISD.
