What's the best isolation system?

Vibration isolation is a two-way street 🔛 That’s why a vibration isolation device can be an upside down pendulum, for example. It’s the combination of the mass AND springs that is the key, not just the springs or the airsprings. For example, an isolation device underneath the speakers does three things: (1) prevents mechanical feedback to the front end electronics via the floor, (2) prevents low frequency seismic type vibration from entering the speakers from the floor AND (3) reduces cabinet resonance. It’s three, three mints in one! As fate would have it vibration isolation DOES reduce self-induced vibration. If there was no such thing as vibration isolation they wouldn’t have been able to reduce the background noise enough to detect gravity waves, the amplitude of which are on the order of the diameter of an atomic nucleus. Hel-loo!

What I don’t quite get is why GK doesn’t just come out and show us all his great ideas. So we can, you know, decide for ourselves. Is he being modest? Or is he hiding something?

Here’s a thought- how about you decide? Here. Take a look. http://www.machinadynamica.com/machina24.htm
Gosh. I can hardly understand why that is "no longer available". What do you think?

That image by the way, according to GK is not his system. There are no images available anywhere on the net of his system. He claims that is a picture of some guy in Sweden. Who supposedly bought this thing then paid for shipping to Sweden. Because that’s where you have to go I guess to find audiophiles dumb enough to have exercise weights and Firestone air springs shipped clear across the Atlantic, Sweden. Right.

But hey, if you don’t like that one he has others. Flying saucers. Morphic Messages. Teleportation Tweaks.

I worry some may think there’s no way, no one could be so kooky, must be making this up just to insult poor GK. Not even.

there is passive, that in essence is a spring. it floats, settles, overshoots, and is soft. even the best possible passive isolation works like this.

then there is active which reacts to perceived resonance; it’s stiff since is can start and stop. passive cannot start and stop. at it’s best it can only self level.

active is very effective at low frequencies, but over 200hz it’s benefit diminishes.

passive struggles to attenuate at really low ’ground noise’ frequencies (under 5hz). it get’s down there but it’s level of attenuation is marginal. that is where active is ideal. OTOH passive is much better than active at higher frequencies (over 200 hz).

Active might be nice for millionaires and LIGO. Passive is good enough for everyone else. 🤗 By the way, active also floats, settles, overshoots, is corrected, floats, settles, overshoots, etc. Also, if you train a camera on a passive iso device whilst music is playing the camera will not detect any motion.
