Under my tower speakers -- Isoacoustics Gaia, other options?

Thanks for your reference to the video and your own DIY account. Very interesting. I watched a Townshend video and there are some more and less convincing elements to it. The vibration dampening is impressive. However, a couple of things stood out to me.

First, I don't usually walk around my room while listening, and no one else does, either. So that "solution" addresses a non-existent problem.

Second, while the earth's seismic activity is an interesting factor, isn't the person in their chair (and the air in the room) also vibrating, and at the same rate? In other words, if I was to dampen the earth's seismic vibration on my speakers -- but I am still not isolated in a similar way -- wouldn't I be more out of sync with my speakers as a result? It seems like an angels-dancing-on-the-head-of-a-pin issue, anyway.

Out of curiosity I sprang for the IsoAcoustic Gaias for my speakers to compare them to my own isolation platforms.  The Gaias do not completely isolate the speakers like my spring platforms but overall I thought the speakers sounded better with the Gaias.  The accelerometer showed that the Gaia still isolates the speakers- just not as completely as my spring platforms.

That was my finding too, in my set up with my Thiel speakers on my wood floors (a rug overlaying the floor).

I use Townshend Seismic Isolation Pods under my turntable platform and they totally decouple from floor borne vibrations.

I tried the Townshend Seismic Speaker Bars under my speakers and they decoupled them very well, a bit 'too well' in that I felt I lost a bit of "room feel" for the music.  

The Gaias I'm now using under the speakers split the difference: they isolate enough to get some gains in bass tightness and the speakers sounding more precise and "disappearing" but not totally at the expense of making the sound weightless.

I'm not 100% sure I'm keeping the Gaias under my speakers, I may yet end up preferring the speakers back on the floor, but for now they are staying.

I believe isolating the speakers from the floor prevents the floor from being a passive radiator.  That helps clean up the bass and sharpen the images.
