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

Contact Audiobahn via Email. (I think they make the Immortal (?))
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.
