This may seem like an odd question. Has anyone really observed what happens to speaker cones (woofers) as they react to different tones? How about when they are subjected to real musical program? A related question is this: does a cone with a freq resp of, say 40 Hz to 2K behave the same way at either end of that range? At 2K does the edge of the cone have as much excursion as the dust cap? Or does the cone have some built-in flex to allow the center to move more than the edge at high frequencies? I have to know or I will kill myself. Crazy speculation is welcome.
