Where dipoles exhibit cancellation is at either side of the loudspeaker/sub. The back wave meeting the front wave CAN create out-of-phase cancellation, but also in-phase reinforcement. That is true for all dipoles. It is a function of frequency and the distance of the dipole from the wall behind it, so designing in a "bass hump" to combat that phenomenon is not possible unless a mandatory dipole/wall distance is specified by the designer. And you know, Danny Richie designs dipole loudspeakers and subs (though not in a manner that satisfies Davey---see above), and is well aware of all the above.
