dipole affect on apparent sealed cab size

$

...probably a silly question to those who understand but....
I'm looking at a cheap 3" 4ohm FR driver that calls for a 2 liter sealed cab...fair enough. But what if I were to wire a second driver on the rear facing cabinet panel in series and out of phase wrt the front driver in dipole fashion?

I understand the amp would see an 8 ohm load, but do my drivers basically see no cabinet "seal" since one is pushing when the other is pulling? Does this not work as the driver(s) may no longer "see" a 2 liter sealed cab? Thanks for your indulgence.
