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?

@yoyoyaya The point of using spikes as anchors, anti slip, or 'keep level' is not disputed (even so much simpler/cheaper methods are plenty), rather their ineffectiveness as a "decoupler", "damper", or otherwise reduce vibrations. i would even argue that putting a subwoofer for example totally flat on a carpet MAY even reduce the amount of sound emitted from the vibrating (bottom) panel (while it still couples the sub to the floor accoustically). |

@zo6ak Sorry, didn't see that you were trying to quote someone (i.e. missing "quote marks". It was aactuall @viridian who said "Spikes are cheap, try them and they will either enhance your listening pleasure or they won't." and thus promoting the idea of trial and error for 'cheap' things instead of logic/research/physics to narrow down the field. |
