Hehehe. Well, for mid-woofers some of the best drivers on earth are the ScanSpeak Revelator/Illuminator lines. They are pretty advanced though, using a sandwich/resin technology, but essentially paper.
You’ll find these in several Wilson models, among others.
There are also some afficionado’s of the paper tweeter/midrange, but probably not me. :)
It’s not just about the materials. You can make both excellent and also very very bad speakers out of a lot of different materials. The design of the motor, suspension and integration with the overall design matter a great deal.
Personally aside from paper I’m generally a fan of composite materials (SS Revelator included) such as resin/Kevlar, the Focal W and resin/fiberglass. You can make some incredibly light and resonance free drivers this way.
One free piece of knowledge I got was from a slide from Focal, on how they sold their brand. Consumers like you want modernity. The idea that new = better, so many brands will sell you on that alone. Modernity without necessarily an audible benefit, or different but not better.
It takes a very confident audiophile to buy a bargain. :)
