[QUOTE="John Roberts, post: 25682, member: 126"] Re: Home Audio Systems I'm no Phil but... The low mass and high stiffness both seem useful for a HF driver or mic diaphragm. The breakup mode (just a normal resonance mode) in a diaphragm is associated with the wavelength of the frequency in the particular diaphragm material. So if the speed of sound is faster in a given material, the frequency of the lowest breakup mode for a given diaphragm diameter will be higher. JR PS: I guess if we made some diamond coated drumheads, the drum pitch could be silly high. A snare drum that only bats could hear. [/QUOTE]
