The early bird reads the good post. Got to be fast to beat the snowflakes and censors around here. oldhvymec triggered someone with his edifying and entertaining post, now removed, leaving us all the poorer. Such are the times these sad dark days.
Why don’t you just move along if it bothers you so much? Not like anyone is forcing you to read this. Far from it. If you’re not man enough to handle diverse points of view why bully your intolerant narrow mindedness on everyone else? Why not just move along? Please?
The prevailing wisdom back then was vibration flows, and you can "drain" vibrations with sharp spikes that are like diodes, allowing vibrations to flow out but not back in. Huge amount of guys bought into this.
This never made any sense to me. On the one hand we were supposed to believe the spikes had to be sharp to cut through carpet and stuff and go into the floor, the better to rigidly couple or anchor the speakers. But on the other hand these same spikes were supposed to somehow drain energy from other components, or prevent room vibrations from getting into the components. Or something like that. The story changes every telling, no one ever bothering to point out the logical inconsistencies.
To me it seemed most of the vibrations were coming from the components themselves. That would explain why a phone book or other mass placed on top affected the sound. It changed the vibrations of the component itself.
One totally unexpected experience seemed to prove this. Doing a Cone demo one time for a friend, instead of stopping and starting I lifted the CD player to remove the Cones with the music still playing. My friend said he heard the sound change- and become worse- the instant it was lifted off the Cones!
If isolation was so important then surely my hands are more isolation than Cones. It should have sounded better not worse. If sharp spikes was the answer then it should sound better on them instead of being better on the rounded off BDR Cones. Just one of many observations that had me pretty well convinced the key to vibration control was control. As in stopping it. With stiff and highly damped mass.
