Once you are wedded to stereo systems it is like any other marriage - you have to try lots of things to keep it going, and even if you think you have it finally settled you will keep tweaking anyway because the great unknown is always beckoning. It's kind of beautiful really if you can stand being miserable at times.
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?

@mahgister Aside from mass (and materials wilth likely different resonance frequencies), what did you use to DAMPEN (sand filled for example (friction between sand corns converts energy), rubber (ditto), foam (? not sure)). |
I used concrete block as damping Masson top...Fined tuned mass ...With 2 set of springs, one set under speakers+load and one set above the speakers compressed only with the load ... Under the speakers in my sandwiches of materials (cork-Oak-Bamboo-granite-shungite) i add in between one plate of sorbothane patches duro 70 ...One of the best damping materials...Then i use decreasing vibrations materials and also decreasing resonance devices and method and coupling/decoupling principle... I used it also inside my 2 headphones +FoQ tape as damping materials ... https://www.sorbothane.com/technical-data/articles/a-good-damping-material-audio-and-electronics

@mahgister I can see from your description about mounting a Speaker Cabinet you take your investigations into tidying up a sonic quite seriously. I have a substantial supply of Cork Pads, they regularly find a place as a additional tier in an assembly. My interest in Granite has a 30ish year history of using it in multiple configurations in a support structure. On my Cabinet Speakers my the Top Weight is a Large Lead Metal Block rested onto four 1/6" Cork Pads. The Lead Blocks then has approx' 20lb of Steel Dumb Bell Weights sat upon it. Moving this weight around to different resting positions on the Top of the Speaker does have an impact where sonic or box coloration are able to be impacted for the better/worse. I am a ESL Speaker user as well, so the Cabinet / Driver issues are easily by passed if wanted.
