Speaker cone material pro's and con's


Are any of you aware of well-written general discussions of the pro's and cons of various speaker cone materials, for example, paper cone, metal cone (and various metals), polypropylene, ceramic, Mylar, etc.? I am not interested in propaganda for various technologies found on speaker manufacturer websites or opinions offered by audiophiles based upon something they read in an audio magazine, but rather, seek a good, general discussion that is written by a person qualified to speak to such issues (e.g., an engineer or physicist) and that is accessible to a reasonably technology-savvy layman.

I understand that the implementation of a particular cone material is crucial to performance and that it is thus difficult to discuss materials in a vacuum (e.g., how a cone's vibrational mode is dealt with dramatically affects performance), but a good discussion would presumably assume certain standard implementations and still arrive at conclusions.

Any links or recommended readings? Again, I am not looking for audio forum blather derived, for example, from someone's trip to Wilson or (mis)understanding of something written in TAS, but the serious observations of qualified authors.

Thanks in advance.

If you want a well-written discussion of cone materials by a professional engineer who is not writing on behalf of his employer, I suggest you join the Audio Engineering Society. I did, and to me access to their published papers is well worth the hundred-something dollars per year.

I could write about some of the pro's and con's of different diaphragm properties and profiles, but I don't meet your criteria, being both a manufacturer and non-engineer.
