Spider question

[hdave 10+ year member]

Hey, i got a Beyond Audio Inhuman 15 Quad 1 ohm.

In WINISD there are different t/s specs for the single and dual spider versions of the sub.

How do I know if I own the single or dual spider version of the sub?

and im having trouble building a loud ported box for it with max dimesnions of: 15.5" x 17" x 20" tuned to 36Hz or so.

Can anyone help with that?
