IsoAcoustics Isolation Feet - Does it really make positive effect or fancy accessories

[Thomas_A]

Look, i tried these sylomer pads for speakers 15-30kg... My speakers weight is 23kg...
The cabinet is vibrating less, the stoneplate is vibrating no more...
But the resonce noises from the chassis frame now arise at a lower volume... Its clearly there. Im not imaginating it.
When i remove them and replace it with those small thin hard shims, these:
View attachment 468177
The resonant noises that disturb me at high volumes are gone.

I might not have the correct physical explanation for it....
I dont give a heck.

I just want it to as good as possible, i drive these speakers over their limit, and are not the newest.

And yes "no measurements"... What you give about? As long as i dont disturbant noises, its good... When i hear them i address and whatever helps it.
I dont know why, thats ok, and if you dont know why its ok for me too.

These are cheap speakers... The feature biamp, but most people not use it, but choosing high crossover.
These are not initially good speaker to go that volume.

Probably new better speakers would be best solution.
Thx, i know that, now have a nice day, please.
Im outta here... The sylomer pucks were a waste of money.

If your sylomer pads made your "cabinet vibrate less", they did the job they supposed to do. The rest is up to the speaker.

Without measurements?? :/



Oh boy.

¯\_(ツ)_/¯

This same poster tried time-aligning subs by putting his hand on the woofers while playing music.

Goa... And my fingertips... goa features very high BPM basslines... So i simply played high volume and then i felt with my fingertips on the bassdrivers if they are pushing out their driver same time.

Im not a perfect machine but i got it propperly time aligned the subs in the stack and the substack with the frontspeakers

A troll it seems.

You were right, i was wrong.
The green 55 sylomer pads (15-30kg) arrived.
It it very "swammy", touch it with a finger now and the speaker moves in all directions....
The stoneplate does NO more vibrate... And the speaker is calmer too... But doesnt make a difference for the resonances inget from the aluminium-chassi-frames
Still its good... Im gonna use it.
But the wobblyness of the speaker is kinda weird.

Complete decoupling risks introducing rocking modes into the speaker while playing, which come with phase and amplitude modulation distortion.

I think probably sincere but misguided.

Rocking only occurs at the mass proportion of cabinet/driver. If a cabinet has 1000-fold more mass than the driver, the linear reaction is down at -60 dB. I.e. Insignificant.

I gave up on my Iso Acoustic Iso Pods. I couldn't get them to actually make a positive difference.

 

[olds1959special]

I found that by removing the top part of the Iso Pod, I could use it as a platform that goes in between my speaker stand and speaker, and this is actually stable enough and seems to make a slight improvement.

Just stumbled on Archimago's post from 13 September 2025:

Do loudspeaker footers make a difference? Inexpensive aluminum alloy "isolation" footers.

A blog for audiophiles about more objective topics. Measurements of audio gear. Reasonable, realistic, no snakeoil assessment of sound, and equipment.

archimago.blogspot.com

They make an objective/measureble difference, but....
"I would not shout from the rooftops about easily audible improvements. My 2-channel and multichannel playback sounded great before the new footers and it still sounds excellent. Whether specific tracks, artists, vocals, percussion parts, etc. now are reproduced with a better soundstage or if the bass became "tighter", I cannot say....That is, without immediate A/B comparisons to detect subtle effects if any, whatever change is within the "circle of confusion" of a complex audio reproduction system."

Honestly I think Archimago was far too kind in his conclusions there. But sure, if you're terribly concerned about the absolutely minuscule vibrations that he did measure, stick a couple of extra rubber bumpers on the bottom of your speaker. Or whatever it was Archimago bought if you're concerned about aesthetics (though I think those discs are distinctly worse than just the stock footers on those Paradigms, but there's no accounting for taste).

Yeah, they don’t exactly elevate the look of those speakers

But, I think that the conclusion is fair. They actually do what they claim - reduce vibrations, so not snake oil. They don’t make things worse. Don’t spend a lot o money on them.

There is nothing new here though. It has been known for decades that soft feet/decoupling reduce vibrations, and that this can be done cheap. If you want to spend some money, around €15 should be the maximum needed for a set of two speakers (8 feet).

FWIW I didn’t notice any audible improvements, nor did I expect to, but I have found it transfers less energy into the floor after using the acoustic feet. Certain songs had bass/kick drums that could be heard as a pulse in the room right below my speakers, and now it’s not noticeable.

Thanks for sharing. I use washing machine pads. They are not soft, but they make the speakers more stable (important because cats).

The new height adjustment feature of the Gaia Neo series got me to bite and order a set for my Ascend Acoustics RAAL towers. I'm skeptical that I will be able to detect an audible difference, but may decide to keep them based solely on adjustability and looks.

I have GAIA feet on my AMT tweeter tower from Philharmonic Audio. I like the look but it's just ornamental.

Let us know of you hear a difference.

They just arrived and I got them installed. They look great, make adjustment on uneven flooring much easier, but I have no way to A/B test speaker feet quickly. I don't think I can hear a significant difference (still need more time), but without a quick switch A/B I can probably never be sure.

 

[GabrielPhoto]

Do you think it's possible that some important things related to audio reproduction are not measurable by modern testing methods? Has that thought ever crossed your mind?

The usual reply from believers....if that is the case, then a simple blind test will prove that the changes are real and that measurements failed to detect it...yet all the believers fail miserably under blind tests, followed by sad excuses...that is IF they even dare to test.
So on one hand you have FACTS and on the other anecdotes lol

The equipment performance is completely quantifiable, no question there. A user's enjoyment of the equipment, not so much, since subjective reasons for the choice of particular gear comes into play. Appearance of the equipment, pride of ownership, ownership group acceptance, brand name popularity, and possibly other factors come into play. Closing the eyelids hides those.
