there are different kinds of bandpass boxes as well. different orders.
The 4th order bandpass is basically a driver placed in a sealed box with an identically tuned port on the other side of the sealed section. So basily you have a sealed enclosure behind the cone and a ported enclosure infront of the cone
The 6th order bandpass system is similar to the 4th order bandpass system , except in this case both the front and the rear enclosures are ported.
The vibe ac series is 5th order, It uses two sealed enclosures behind the subs, and one enclosure in front that they share with 2 ports.

Apparently both enclosures should be slightly smaller than if you where just making a normal one. But i dont know how "slightly" smaller this is sorry.

The vibe blackair has Recommended Enclosure Volume: 1.25 Cu.Ft. Dont know if this helps
