Looks to me like the real contributor was Pjotr in this thread. There always seams to be someone with an EE degree in the bunch.

I find the color scheme over there makes it really hard to read -- one of the reasons i've not spent a lot of time over there. I like this one better.

I see.
Seems like a big part of the trick,
is to find the right quality of the isolation material,
in relation to the weight it is going to carry.
Yes, using suitable springs (coil or magnetic or other) the mass/spring stiffness ratio determines the degree of isolation and resonance frequency.
With the valve springs I mention, the vibration isolation is such that for equipment, if the shelf is banged with the fist, or buzzing like crazy due to speakers running loud, virtually zero vibration can be felt on the underside of the amplifier.
Also with the speakers running loud, very little vibration is felt on the table top underneath them, even though the speaker cabinets are buzzing like crazy.
These springs are machined flat and square top and bottom, so are perfectly stable.

I find this is a cheap and very effective soloution, and better than mounting techniques that I have tried previously.

As Frank mentions, a simple slab or blocks of foam rubber, can work quite well too, and is equally cheap.
Indeed this has saved me the embarrassment of a skipping cdp at live shows during intermissions.

Eric.

Math is still impressing people?
How hard can it be to impress people with something that can be culled out of nowhere ?
I'm always impressed by formulae,you can easily paste them in from any net source and they are infallable.
Most impressive,great contribution...

From understanding these you can really tell what an isolating platform is going to bring you.
I'm still impressed.
Then again,most of us never went to school.
We don't know anything about anything and have never heard about magnetism.
We are all deaf too,so you better don't waste your precious time.

Nah,don't worry.You earned a price for the most intelligent post ever.

Cheers,
