Speaker isolation - spikes on puck, springs, sorbothane

Another thing to keep in mind:  Springs isolate, rubbers dampen.  And the damping properties vary with weight, frequency input and durometer of the rubber as well as formulation and temperature.  Rubber materials will affect the sound of a stereo component,  no question; but how it impacts the sound and interacts with a component can get very complicated.

The GAIA footers look like they use a combination of spring isolation and rubber dampening.  I think that is why they sounded better with my speakers vs. straight springs.

The other option is Townsend speaker platforms.  They utilize spring isolation.  I do not know too much about them.  I have never seen a set first hand but that was my inspiration for making my own speaker spring platforms.

I own Townshends for some speakers, but I am an Isoacoustics dealer and have used them largely under speakers and components for the last 7-8 years even before I started dealing them this year.

Townshends are really great, in my experience, for rear firing or sealed speakers. Not so much for speakers with side firing woofers and certainly not for bottom-firing or bottom-ported speakers. Otherwise, on a suspended floor, they typically will outperform Gaia I for your Wilson, but they will also take up more space and be quite unsightly.

The Gaia I will come quite close in performance for a much lower cost. In any case, on a suspended floor, you’ll want to decouple your speakers and not add basic resonance or dampening. 

Thank you. I like the idea of the Gaia. The Townshend is also aesthetic, perhaps with a lower speaker rise. The Wire Rope style is intriguing (isolator.com/wire-rope-isolators/sm-series/). Give it a lookup. I found them at 40 lbs per isolator, which would work fine on the Sophia.

You are likely to get as many suggestions as posts.

My suggestion is to give these a try.  They will give you an introduction to decoupling/isolating, and it may be the only $28 you need to spend.  Think about weight distribution, total weight, and a mild tilt back as you could either try 4@2” under each speaker, 4@2.5”, or 2.5” in the front (the drivers are bolted to the front baffle so there is probably more weight distributed to the front), and 2” in the back, which is what I use for my 175 lb speaker/stand combo.

@mitch2 I don’t see what you are suggesting.
