Speaker vibration isolation


P.S. Audio has a video on YouTube, “RMAF 2018”, on Isoacoustic’s speaker vibration eliminator. The demonstration was impressive. Does anyone have experience with these, specifically the ones that replace the spikes as opposed to the stands? Thank you.

I would image dipoles do not produce much downward force compared with box speakers, thus reducing or maybe eliminating feedback problems. Whether dipoles benefit from isolation themselves, color me skeptical.
I feel it’s only fair to interject that whilst cement slabs do have their advantages they are nevertheless subject to the very low frequency vibration produced by the motion of the Earth’s crust, which pushes the cement slab just a tad. That is why mass on spring isolation is effective on cement slabs.
For starters, getting back to reality for a moment, Vibrapods are not (rpt not) designed to support objects with high centers of gravity. You know, like speakers. They the Vibrapods don’t have enough lateral support. That’s why you see a lot of designs for speakers with the capability for obtaining very wide footprints. It’s to get the necessary lateral support. Otherwise the speakers would just flop over.
Without mentioning any names, somebody is not yet on board the mass-on-spring vibration isolation train 🚂. There is a reason why some isolation devices are more complex and more expensive than others. For example, let’s take two parameters for example, resonant frequency and number of directions of motion. All aboard the mass-on-spring isolation train 🚂Toot! Toot!
