To me, the big takeaway from this discussion is the importance of using drivers that permit the crossover points being moved out of the heart of the midrange. I've heard one way, two way and three-way systems utilizing wide range drivers that permit this, and when properly implemented, such systems sound terrific. My local, Washington DC audio shop, Deja Vu Audio, builds custom systems based on this principle. They have one and two way systems using full range dynamic drivers.
But for my taste, it is their horn-based systems that are the best, and they employ horn/compression drivers to handle the bulk of the frequency range. Some of their systems are crossed over as low as 200 hz to the woofers and around 10,000 hz to the tweeters; that is a wide range being handled by the midrange drivers. Horns that can go as low as 200 Hz are giants, but, Deja Vu has some folded horns that are reasonably compact and can work as low as 500 Hz.
The BIG plus of both the horn and wide-range dynamic driver systems is that they are all very efficient, which means they can be driven by low-powered tube amps, another specialty of Deja Vu Audio (they make their own low-powered tube amps or sell brands that specialize in tube amps--Audio Note, Synthesis, Conrad Johnson).
Everyone who doubts that a wide-band driver can sound good even as a single driver system should make the effort to hear some of the systems made by Charney Audio, Voxativ and Cube Audio; they might change your mind.
