nodes

I've written this before: by the laws of thermodynamics, energy can not be created or destroyed. All we can do is to alter its amplitude or frequency, but the energy still remains.

Thus the issue is how break up the nodal patterns into something more amorphous and random instead of being one set pattern.

One thing to note is that the darker areas represent the area where the plate is vibrating more, hence the salt is moving to an area where there is relatively little vibration. One thing I notice is that the area between corners seem to have the most dark spots and hence must be vibrating more ( at least in many of the patterns)

When using cones under components I find that placing them under the roughly midway points from the corners seem to generate the best overall sound: more even and dynamic and certainly more extended over the frequency response. I certainly do not place it perfectly centered however, and my guess is that it breaks up the patterens even more so.

YMMV and FWIW
