Gotcha, Duke, thanks. That's kind of what I recall too. Earl is a really smart guy, but I think what he wrote about cone motion painted a picture with very broad strokes. It's kind of like providing an "analysis" of what's required to get a man on the moon by saying "build a rocket." Not that cone flex is quite as complex as space travel, but you get my meaning. It's one thing to admit that a loudspeaker cone isn't a rigid piston, another thing to estimate its average behavior in breakup with a small number of forumulas and still another thing to try and make an accurate model that actually describes the complex motion of its surface. So while I think the world of Earl, I don't think we can credit him with modeling breakup modes just yet.
