if you want to achieve 2ft3 the you need to add in other displacements on top of that 2ft3 like port, sub, bracing, wood..

x2, you want the 2ft^3 to be the net volume that the sub will see after it's all said and done.

So, in addition to? I.e. The Volume of the port is not added in the calculation to come up with the net volume?

you have gross and net volume. your net is how much the sub will "see", gross is how large the box is altogether.

net = gross - all displacements (port, bracing, sub displacement, etc.)
