Vandersteen has spikes and footers
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?

I also use ISO Acoustics Gaia under my speakers, and there is no doubt that they improved the sound over spikes. They don't decouple fully, but work well in that direction, and, along with the likes of related Townshend products, reduce the "smear" that results from vibration, and also improve the focus of bass response. The disadvantage, at least for some (not in my case), is that hard-coupling devices like spikes do transmit more bass energy to the floor, and some listeners prefer to have that visceral feedback, which is reduced with the use decoupling devices. |
