I have mucho experience with all manner of cones, ever since I started developing my Sub 1.0 Hertz Nimbus platform which has been a while. What I found out was that the two critical characteristics of cones are hardness and shape. The very best cones, like ceramic Super DH (Diamond Hardness) Cones from Golden Sound, are both very hard have a very ballistic shape. They are more open, more natural and more dynamic. By contrast, BDR cones (carbon fiber) are relatively soft (on the Mohs scale of Hardness, I.e., strong but not hard, AND they have a shallow, much less ballistic shape.
