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!
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.

specifically the ones that replace the spikes as opposed to the stands? Always spike into a cement slab floor, especially if it’s laid on mother earth. Good test if you can feel through your bare feet drop something heavy dropped on the floor, if not spike into it, if you can feel it don’t spike (couple), as the floor will become a sound board for the bass notes and muddy the bass. Best in this situation is to isolate (decouple) the speaker from the floor, numerous ways, cheapest I found without being ripped off by "audiophile products" is with heavy duty "Sorbothane" pads like these, there many if you search, 4 of these "70 duro" will take a 52kg speaker. https://www.ebay.com/itm/NEW-SRM-TECH-SORBOTHANE-ISOLATION-RINGS-HEAVY-DUTY-70-DURO-4-PACK/332856500... https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313.TR2.TRC0.A0.H0.Xsorbothane... Whatever you do DON"T put your speakers on springs, they'll wobble around like jelly, and your image will be shot to hell. Cheers George |
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. |
I too believed that coupling (spiking) them through the carpet to the slab would be the way to go...until it wasn't.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. https://s.hswstatic.com/gif/house-slab.gif Cheers George |
