Thanks zheka, that really is good stuff. I didn't realize how much or at least the extent to which stading waves affected the cone until now, excellent visualization of those sound waves. Wayne's explanations are always a joy to read...I need to frequent his forum more often. Thanks again!
I think normally woofers are not driven that far above intended frequency range.This example may be a bit too extreme.
But I find this kind of self organizing patterns mesmerizing. Have you seen this one?
Love it, I could watch that for hours! I've always been drawn to kinetic art and it's examples like these that are visually striking and I agree, they are quite mesmerizing. A bit off topic, but some of the magnetic ferrofluid demonstrations on YouTube are excellent as well.
