What you're essentially doing when you do this is giving it 180 degree phase shift and increasing the volume the chamber as the part sticking in takes up volume. However, this is the theory, the physical results have more nuances to them.
There's a design where you can actually use two drivers face to face (wired 180 out of shift) where one would think you would get 2x of what the single is doing, but the response changes so it's not as simple as 1+1=2. But all this can be modeled so it's not guesswork.
EDIT: almost forgot to ask is this designed wired with a reverse polarity? Or does it still keep the normal wiring of all the other designs?

Its called isobaric. I believe its to squeeze more power out of a smaller box.
Only seen them at car audio shows
You have more power handling but x-max and therefore Vd doesn't change. The biggest advantage is that the box can be made 1/2 the size at the expense of twice the cost and weight. In car audio, space is in usually shorter supply than money. Top competitors are also sponsored (free drivers) and if they use twice the drivers for their car to win then all the masses aspire to copy that design (increased sales).
