making a box for my 12'' dc lvl 4

[socialstealth 0]

I think I'd like to tune it to 30 hz.

I want to make a double kerfed slotted box with all 45 degree angles inside.

whats the displacement of a 12'' DC lvl 4?

what should the diameter of the port be?

This is going to be the first box I've ever built

any tips will be greatly appreciated!
