Speaker vibration isolation

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.

@georgehifi   My speakers are sitting on plush carpet with pad over a "floating concrete slab". I too believed that coupling (spiking) them through the carpet to the slab would be the way to go...until it wasn't.

After decoupling there is no going back. Cleaner, clearer sound.

If it was a proper building slab of concrete some 2ft thick around the edge and some 6'-8" thick for the rest, if this wasn't best, then something else is at play.

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.

So, if I am to understand the dialogue, Martin Logans currently spiked to suspended wooden floors should benefit by a decoupling agent like the Giai 2. Right?
