Isoacoustics Gaia and speaker wobble


I have installed Isoacoustics Gaia II isolators on my Focal Aria 936. Initially I had some issues installing them but have resolved that and they are on tight. I have thick plush carpet so the isolators are sitting on the carpet spikes that Isoacoustics offer as well. When I lightly tap on the side (and back) of the speakers near the top, the speakers wobble slightly, but then return to position. Prior to installing the isolators, I used the stock spikes and the speaker did not move as much, hence the questions. 

Also, I put a bubble float on the top while playing the music loudly (with a high level of bass) and the bubble did not move, so I’m thinking that is key. I actually sunk a nail into the carpet to make contact with the hardwood floor beneath and then compared the length of the nail to where the isoacoustics carpet spikes go in and it appears deep enough.

Has anyone else experienced movement they consider normal and in general, is a certain amount of movement expected. And, yes I asked ChatGPT, but I’d like actual experience of owners. :-).

I know pictures help, so see below. In the first picture you can’t really see the spikes. The second I show them. You can hear them push through the carpet when I step on the plinth.

Thanks very much.

I have been very happy with the performance of a set of AUVA -70 speaker isolators from Stack Audio. I'm using them with my Aspen FR10 speakers on a carpeted floor in a first-floor living room that sits above an open basement space below. Each AUVA isolator (using four AUVA-70s under each speaker) is fitted with three spikes, and the spikes can be selected in whatever length is needed to puncture through the carpet and pad to reach the plywood flooring underneath. This results in a much more stable connection to the floor than could be obtained with the stock spikes that came with the speakers and rested on top of the carpet surface.

However, as you know, a more direct connection between the speaker and the floor may sound worse if it simply allows more vibration to be transmitted back and forth between the speaker and floor. The nice thing about the AUVA isolators is that they include compartments that control vibration transmission a lot better than a simple spike can.

@hazeloop if you can't get the Gaia isolators to work well enough, you might want to try out the AUVA-70 or AUVA-100 isolators.  

@hazeloop I would expect that the sound might become a bit more defined, which could come across as flatter. The Gaia’s increased my soundstage as well. I always take these changes slowly, and leave them in place for a couple weeks or more before I decide whether I like them. Looking at the pictures where I can see one footer it seems you have them configured correctly, but be sure the IsoAcoustics label faces forward on all the feet, they are directional. 

@zlone - thanks much. Yes, I definitely have the logos facing forward. I know micro tweeks can be done where they can face backwards also. I'm now anxiously awaiting on the longer spikes mentioned above after exchanging emails with their CEO. They are supposed to be roughly 23mm long which I'm hoping will penetrate further. We'll see

@sdl4 - definitely an option with the longer spikes. Thank you. I'll wait for the pre-production version from Iso and then re-evaluate.

@hazeloop I expect you will hear the difference once they are properly anchored. I discovered how important that is, and what the Gaia’s really do, when I put slippery material under each foot so that I could do some fine positioning on the speakers. I had it that way for awhile and I noticed some of the magic had disappeared. Removing the material and letting the Gaia’s stick to my hardwood floor as they are designed to do brought back the positive effects. Keep us posted on how it goes.

I guess that would depend on manufacturing tolerances.  Normally facing forwards or backwards is fine, but not skewed or sideways
