Kevlar, Polypropylene, Carbon Fiber sound differences

Rodney Gene · 6th October 2005

Anyone have a link where I could learn a bit more about the different sound characteristics of these different cone materials?

So many great monitors and so many different materials.

I just bought a pair of JBL LSR6328P's and they have a fuzzy paper looking graphite cone. Totally different than anything I have owned before. Wondering why JBL uses these and not something else...

Thank you.

Here are some articles I could remember, one set from B&W, the other a reprint of an article by the late John Dunlavy. Neither too in depth, but a fair start.
