Atkinson got it wrong about "phase coherence." The difference in the group time delay between drivers can be compensated for by an appropriate digital time delay for the signal going to the tweeter (requires a separate amplifier.) Even without time delays the relative group delays can be reduced by making the tweeter heavier and the woofer lighter.
That being said, the whole idea is stupid because even when they are vibrating in phase, unless they are concentric and have the same center of propagation, there will be interference patterns due to geometric considerations. It's like dropping two rocks in a pond and they hit the water at the same time but not in the same place. This is wave mechanics 101. The only way to test for the audibility of phase coherence is to build a speaker that is coherent but adjustable so that it is not coherent and then switch the circuits between them. Otherwise there are far too many variables to say yes or no. Fortunately this buzzword fad is history and now the industry is on to new and different silver bullets.
