Let me apologize for the rushed post. That first sentence makes no sense to me either. My point is you can make general staement in isolation about the material used. For instance so many mill of a known alloy of aluminum will weigh a certain amount and be stiffer than many doped papers. The question is what parameters are vital. Do you think calling our non phyical engineers or non compound chemist's contributions blather? Speakers are tricky to get right. The materials used make a contribution but in the end it is the sum of the parts. Good speakers obey the fundamental rules and then the builder, who is on a path of good intentions hears them and spends a lot of time voicing them. It is an imprecise science.
In order to give this fellow a reference that is truly helpful you have to ask what does he ultimately want to know. The early speaker design books tell you more about what the resultant sonics are likely to be. I personally don't think dustings of diamond on a cone or Be or Ti fundamental.
