Good quality single driver speakers tend to excel in coherency, which to me is a key ingredient for the highest quality sound. That to me alone explains the attraction, regardless of the downside. All designs have advantages and disadvantages. How those factor into a final value judgement is completely up to the individual.
There are also many time and or phase "coherent" multi-driver designs out there to compete. Ohm Walsh/CLS, Thiel, Kef UniQ, Tannoy concentric driver designs, mbl, for example, are some that come to mind. I currently own both Ohm Walsh/CLS (coherent line source) and kef UniQ-based speakers (ls 50s and ls 50 metas).
I’m a tough sell personally for any speaker design that is not inherently "coherent" .
Large speakers with multiple drivers all spread out seldom cut it for me in comparison. Requires a very large room for those to integrate time coherently at ones listening location.
