Vibration - What are the Main Sources?

Millercarbon,

Do you honestly believe that I, and the others named on whatever letter you’ve received from some nut case had anything at all to do with it??!!
Just because said nut case decided to use our user names, you truly believe that we all somehow got together and conspired to threaten you?? You truly believe that enough to print our user names on this thread as if we did??! Good God man, think a little.
Get a grip. I had zero, and I mean ZERO to do with whatever it is you received. Yeah, we’ve all nothing better to do with our time than to forge a secret cabal against you. You are that ingrained in our lives. Ridiculous.

BACK ON TOPIC:

This brings up the question that since literally everything vibrates,
is it plausible to posit that the higher quality the equipment, the more sensitive it is to audibly transmissive vibrations, therefore it requires more sophisticated damping than lower quality equipment where a more extreme amount of damping is not required to improve the sound as it has reached it’s improvement threshold?

I believe the premise is that the speakers are resting motionless on the springs at a specific tension and the function of the spring is to isolate/dissipate vibration.

I believe the springs are to isolate the speakers not from their own vibrations, but those from external sources. If the tweeter and woofer did not move, you would have one quiet speaker!
