>Why do you think having a very flexible support >would 'dissipate' energy? Did you ever hear a mantle clock with a loose chime? Where a solidly mounted chime will donnnnnngggggggg, a loose one will donk. It will still make noise, but if you want sustain and clarity, you need either a solid mount, or a self contained balanced dynamic system like the tines of a tuning fork of tone bar. In the tuning fork and tone bar, the energy reservoir is the tines, or body of the bar. In a piano, the energy reservoir is the string plane, and if all the initial string energy is being spent waving the rim about, not much is cycling back to the strings to sustain the mutual feedback process. Like the clock chime that goes donk, the energy is quickly absorbed by the system. In physics, work is described as the product of force and distance. If the force is spent in movement that isn't partially used to replenish the energy storage reservoir (strings), it's gone. The work is done and the energy spent. Motion that doesn't support sound production or the energy feedback cycle is wasted motion, and drains the system. Ron N
