If you are using 1" wood i'm coming up with a port length of 32 inches to achieve a 32Hz tuning. You're gonna have to make your port a bit skinnier in order to achieve the length to area ratio you want to get your tuning since 32 inches is gonna be impossible to get when the box is only 24 deep. Either way you are looking just over 4ft^3 after all displacement. This Torres calculator is about as good of a tool as you can get when building a box.



Edit: If you were to go with a port of 4H X 10W X 15L you will get 31.95Hz and 5.22ft^3 AFTER all displacement.
