Speaker vibration isolation

The Gaia I's were of great benefit to my speakers even on a cement slab floor. One note on the Gaia's is that they are directional and need to be properly oriented with the label either facing forward or backwards. Like many have already mentioned they come with a 30 day return policy, so they are well worth a try. I was prepared to send them back if they didn't provide a noticeable sonic improvement......they've never left my speakers. Lastly, I have my installed with the Sound o City outriggers which look great together and add more stability.

Correct I have Monolith III's on a suspend wood floor, my bass cleaned up considerably when I decoupled them from it.

Blu Tack between my suspended wood floors and my Infinity RS1b mid/high tower feet. Reasonably priced and works well. 

here's an objective test some people may find valuable, though it is for studio monitors rather than floor standing speakers.

My guess would be that floor standing speakers have even more weight (to driver ratio) and less vibration.

I did listen to a demonstration of Focal speakers with and without isolation products applied at Rocky Mountain audio Fest in Denver Colorado (2018). The isolation product was impressive, in that it seems to clear up the vocals, but it also raised the speaker a couple of inches, which means that the Tweeter was in a different position, which could lead to the same effect.

Just wanted to add my experience to those who have found a significant benefit when adding Gaia's to speakers formerly spiked to a concrete slab.  I have no explanation or technical expertise, but the improvement in image clarity was not small and (to me) well worth the cost.
