As mentioned in this post: http://www.hometheatershack.com/for...-2x18-page-ranking-200l-new-3.html#post154701 , when measuring a subwoofer (like, outdoors, not in a room), do you not need to take into account everything that emits sound? That includes the driver itself, the PR(s)/the port. Otherwise you wouldn't get a realistic response, no?
