Speaker Spikes - Working Principle

Vibration damping obvious makes sense (in speakers just as well as in cars). 

That involves 'killing' (converting into heat, through typically internal friction) kinetic energy. So any sort of elastic material (rubber has lots of internal friction) makes sense. 

And then there are spikes. Using a pointy hard object and pair it with a softer, elastic material (to deform, and kill kinetic energy) can work; think metal sharp spike into carpet or wood floor. 

But what is the idea behind pairing fairly unelastic metal (brass for example) with similarly unelastic (brass, stone, etc) material (example photo provided)? Only thing I can come up with: LOOKS good and makes owner feel good  thinking its an improvement (works only for Audiophiles though),

Even more curious: are they ENGINEERED "spikes" (vibration dampers or shock absorbers) for speakers that are TUNED for the frequency (and mass)  that needs to be dampened? Can piston style fluid dampers be designed for the high frequencies (100, 1000, 10000 Hz) using geometry, nozzles size and viscosity of the fluid?



@ditusa Thanks, that explains why spikes (or other rigid 'couplers') DON"T work. A suspected. The acrticle does NOT offer solutions to decouple.

Norman Varney’s solution for decoupling are Equipment Vibration Protectors see below:


See previous post below decoupling the speakers from the wood floor:



I don't know if this qualifies as a speaker spike, but I found that using the ISO- Acoustics Gaia 1's under my Clarisys speakers to be a big improvement over just using the aluminum feet. I also added the carpet spikes under the Gaia's and found that to be an improvement.
