Appreciate dude, but this is a sealed box for only for only 1 sub. I just need to know the volume the for the box.

That was a ported box, it even says 21 square inches port area and 15 inches port length.

Your airspace is going to be a bit on the small side for pair of 12s. Doesn't JBL have box plans/specs on their website or published with the sub? Have you attempted to use WinISD? It is free software and can help you see volume and port dimensions for desired tuning.

I'm getting 2.75 cu.ft total for 2 of the 12's. But it models better with an aero-port that is 6" x 16.75"

I would get with @Buck and have him design your enclosure
