Maybe with the Dunnoy, we have a “working” point source? Perhaps this type of “point source” puts audio playback artifacts in a better location than with the traditional spread of drivers?

I think this is certainly a distinct possibility. The audio lobing that occurs with multiple drivers is absolutely one type of audio distortion/artifact that is clearly audible. Vertical speaker alignment and driver time alignment lead to consistent audio lobing patterns, but do not eliminate them. While vertical driver alignment helps, it relies on the listener keeping their ears in a vertically symmetric position. Small dynamic changes in listener position are unavoidable. Head tilt will allow these distortions to emerge, more prominent is some frequencies in a semi-chaotic fashion. 

I think this is only one of many types of audible distortion/artifact that emerge as a result of the physical limitations of speaker design. The "Dunnoy" is doing something right, bringing the sound closer to the listener's perceptual requirements, and it may include "a working point source" but there is probably more to it that this.
