GK was one of, if not the first, proponent of springs for isolation on Audiogon. Do a thread search.True he speak with me of that.... And i bought set of springs to make exsperiments with.... And i discover how to decrease the resonance in my box speakers with a dyssimetric applying force between the 2 sets i install on each of my speakers using a different compressive force on each with great results...
But he use the spring incorrectly, unsing only one set under undamped box speakers...
