There is a reason why single driver speakers are a niche market, at least for hifi systems. TEchnology has probably improved but again those darn laws of physics just stand in the way. HEnce the proliferation of other designs.
Midrange is where most music happens so nothing wrong with the tradeoffs involved. Limited frequency response makes finding a suitable amp an easier task, not to say that any two will sound exactly alike.
Its all about tradeoffs. Dale Harder's modern Walsh drivers probably have the best chance of pushing the limits but I would still be concerned about power needs, overdriving them, or just being able to stay in good working order over teh long term. All those things that limited their mass appeal in the first place.
