I've seen that are nothing more than sorbothane that I can and have purchased on McMaster-Carr relatively cheap.
My Studio2s are going to be sitting on mahogany floors. I've considered using the included spikes using the nylon ends and placing them 1/4 thick high density sorbothane.
Not very attractive except for the price
I've used the same material under my front load washer and it positively stops the washer from walking.
Also on my DIY equipment rack which is hell-built for stout.
BTW, if you are unfamiliar with the M-C site I highly recommend it for all manner of hardware.
As always, I'm not looking to spark a contentious back n forth about snake oil products and I'm not going to argue about any of them.
I've tried one of the ISO-acoustics products: the iso-pucks.
Like you, I find the idea of isolation for something like speakers to be plausible, yet I'm also skeptical (as I'm skeptical of many high-end claims, especially of the "tweak" variety).
I bought some iso-pucks to try when constructing a new stand for my big new turntable, to try as a layer of isolation. (Again, isolation from vibration for turntables seems a good idea. After all, they work via amplifying vibration, and it's not for nothing that a large goal for turntable manufacturers is reducing spurious vibration in the design. Claims that amplifiers, CD players etc. benefit similarly from isolation products do not strike me as being so credible).
I didn't get quite the results I was hoping for from the iso-pucks. Another set of spring-based isolation pods proved far better in terms of felt and measurable isolation from vibration. But since the iso-pucks are sold for use under speakers as well, and my Thiel speakers were a suitable weight for the iso-pucks, I tried placing the 4 pucks under one speaker to compare. I'd had an in-stores of the isoacoustic Gaia footers where they do a similar demo - one speaker on the footers, one off, and switch the balance between. I did hear a difference in sound so that was interesting. But the thing is simply raising a speaker is likely to change the sound as you are changing the relationship of the woofers with the floor, the driver height relative to your ear, etc. So untangling a difference of simply raising the height vs actual "isolation" can be tricky.
Also, though the isoacoustic products are stated to be designed to allow more movement "front to back" and less "side to side" (which is why they tell you to place the logo facing you), in simply bending the product around I could not discern any less or more flexing in one direction.
Anyway, my results...at least with my speakers...weren't great. The sound of the speaker did change, sounding a bit more lush in the mids and "relaxed" sounding. But it lost some liveliness in the upper frequencies and possibly because of that seemed a bit less dynamic. The bass became a bit too rich and slightly bloated. I wondered if I was imagining this but every time I took the iso-pucks out sitting the speaker directly on the floor as normal (no spikes) the sound snapped right back to "normal" with tighter bass, and the preferably more open/realistic tone. In my system, I wouldn't choose to use those iso pucks.
So that's my anecdotal report on the iso-pucks. Take it for what it's worth :-)
