Why are concerned with the material used when it is the If its the sonics you are interested in then a discussion hghly scientific of course of the tensile strength of kevlar of a particular type versusthat of paper is meaningless. The entire driver parameters may be what you want that tells you more objectiveinformation.
Technical talk of one material over another is blather with very cone/dome/oval, square, specific data. You might want to know the Qts. for instance, this could be high or low do you know what you want? Because there are advocates for both types depnding on the cabinet design. etc. There is paper that is like leaden cardboord and there is paper which is siff and very light. What question are you interested in answering? Look at the raw driver sites they frequently give specs. You didn't include the Plasma Flame tweeter transducers in your post. But that's a hot topic.
