Then drop four pebbles each a few feet apart, note that there is much more intersecting ripples, producing a very diffuse effect where the peaks and troughs that were very apparent with the first pebble become much shallower, not only that, but the diffusion will nearly eliminate the "wave" effect. And the more subwoofers, the more even and diffuse will be the ripples
Dave thank you now I understand is that true? I used your explanation to spread the word.
