The World's First School of Cymatics
There is an installation I made with subwoofer, some construction and plate which is fixed in the middle. Whatever sound I try to play on the computer or through the microphone does not really make any difference - there is not much happening on the plate. I think the problem might be in subwoofer, or the curveness of the plate. Could anybody specify if subwoofers are usable and what thickness of plate should be for this.
