Kerry, thank you for sharing your paper diaphragm idea. Very interesting. As I remember it, the Cogent diaphragm I saw (and listened to) at Steve and Rich's place was a flat disc of something like fiberglass, and it looked relatively heavy for the application, compared to the usual compression driver alternatives. Withal, used as I heard it, the sound was truly phenomenal in a narrow band around (I think...) 700 Hz. I have no significant experience with the original RCA drivers.
You mention that you use all Class D amplification. Does this mean you also use a "pro" type, digital solution, or something like this, for your crossovers, including LF loading, or perhaps you even use shaping?
Of course, leather suspension is not really a solution but just an alternative. At this point I think the root question is one of movement vs. damping of that part of the cone and whether a particular application (of leather or whatever) happens to address and/or facilitate a particular behavior in a particular, +/- controlled situation.
Best regards,
