you must allow for the subwoofer displacement for an accurate measurement. Most manufacturers will give their woofer's displacement in their manuals or online.

And if you are doing a vented/ported box, you have to subtract the volume of the port as well.

Everyone one is right but for clarification:
Box size in Gross Cubic Feet is the total volume of the box.
Box size in Net cubic feet is the Internal volume of the box after you subtract the space the port is taking up and the sub.
All reliable box tune specs are in Net cubic feet.
