BTL 15s box help

[keith77 0]

Ive got 2 BTL 15s and i wanted to make sure my calculations were correct before i started building. The total room i have to work with is h=23 w=24 l=39inches. Total internal volume is 10.5 cubes, and after all displacements i have 8.65 cubes. the port dimensions are h=22.5 w=4.5 l=18.4 which should make the box tuned to 33hz. can someone check this for me to make sure i didnt make any errors.

Thanks

Keith

Theres a formula but its kind of confusing. I went to carstereo.com, they've got port lenght calculator. Just plug in numbers and it will tell you how long your port should be for the tuning you want. I dont know if its accurate, thats why im tryin to get some help from the pros.
