[QUOTE="ciaonzo, post: 8043262, member: 607015"] I believe that you may be describing a frequency response characteristic more than a driver diaphragm material. That being said, there are badly behaved domes within many materials, but metal ones (mainly aluminum) are responsible for some pretty horrid harmonic distortion problems that are actually outside of the pass band but have a detrimental effect on overall performance when driven hard. Newer designs have offered some solutions to these problems but the effects can still be seen in various plots. Metal domes can sound quite soft and textiles can be harsh, contrary to popular belief. As neo stated, don't get locked in to the idea that you must have one material over the other. Just too many things to factor in. Is it chambered, does it have ferro-fluid (can mask detail), does it have a convex or concave diaphragm, is the surround the same piece as the diaphragm or is it a different material, how wide a bandwidth, how hard will I be driving it, what does the frequency response profile look like, what does the waterfall plot look like, and so on and so on. Check out drivers that aren't offered by car audio vendors, you will come out ahead in the end. If not only in your pocket...
