While we are at it, let’s discuss how little has been done in quite a while to innovate and improve violins, acoustic guitars, and the hockey puck. Surely, new and better materials are available—beryllium has to be better than maple.
How do you know any one approach is inherently superior and that approach is the latest invention? It is simplistic to assume one aspect, like the material chosen for a midrange, is superior in all aspects of performance and that a driver employing that design choice would be best in all systems.
This also assumes that there is a consensus on what sounds good. It is clear we don’t all agree which is why there are many choices out there. For what I like, I have not found one aspect of design that always sounds superior. It is not simply a matter of picking the latest technology, or something that measures well, or any other indicia; it comes down to hearing the gear.
