Any mass-on-spring system works both for vibrations going up to the component or speaker and those going down. What I had in mind is another layer of resonance control that addresses the “residual vibration” on the top plate of an iso platform, e.g., motor vibration, acoustic wave vibration, what gets through from the floor. There will always be residual vibration because the mass-on-spring iso system acts as a low pass filter, so some relatively high percentage of *very low frequencies* gets through to the component or speaker, depending on Fr. Speaker vibration frequencies don’t extend nearly as low as seismic frequencies, maybe only as low as 30 Hz, so in terms of mechanical feedback speaker isolators work very well, indeed, close to 100%.
Vibration Isolation
I came across these the other day and for the price I couldn't pass up trying them. I've spent as much as $75 each for vibration isolation pucks and seen pucks going as high as $900 each. I have to say that these $0.62 wonders work as well as anything I've tried and much better than the cork ones I've seen advertised for $6-$7 each. Even though my VPI turntable has factory cones and feet I did notice an improvement in smoothness and clarity. Too few bargains in high end audio not to share. I now have these under my monoblock amps, turntable and turntable motor. Hope this helps someone looking for an inexpensive way to dampen vibration.
