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?
@goose I just ordered Herbie's gliders and I'm in the exact scenario of your room. What were your thoughts on them versus spikes? Our TV room is right below my listening room so I'm hoping the gliders give a little more bass isolation versus spikes. |
Hello everyone. I have a new company doing specialized acoustic de-coupling products and damping pads for HiFi Audiophile and Professional Audio applications. Check out Acousti-Float.com. Bare with me, new site under construction. I'm currently looking for testers of new products at no charge to you. Please get back to me if you would like to test some of the goodies I have designed and fabricated. Very simple products but very powerful at the same time. Look forward to hearing from you. Hope everyone has a Prosperous and Happy 2024. |
Isoacoustics includes the threaded rods for a lot of speakers (not KEF, but they were quick to send me the correct ones). And you would be correct. I have hardwood floors with wall to wall carpet on top, so if I uses the Gaia’s, I’d need to use their spiky things underneath and they would poke through the carpet and muck up the hardwood floor. So the granite pieces took care of everything. |
