Has anyone here ever designed a custom box for 1 15" immortal sub, or does anyone know the best design and dimensions for one?

They'll give you specs that should work out right.

General rule of thumb for a 15" is about 2.5 cubes sealed or 4 cubes ported (tuned pretty low). 12 is 1-2 cubes sealed, 3 ported. 10 is .75-1.5 cubes sealed, 2 -2.5 ported. These are very broad specs and won't accomplish much unless you have the recommended specs for your sub, but it's a starting point.
