Worth Every Penny
Joe from Palm Beach Gardens on 1/23/2024
These are no joke. They do everything stated and not by a little! Immediately noticed major jump in sound stage width and depth. Walls disappear. Bass is articulated and deep. Easily took down resonances a couple db. The biggest surprise was clarity in mids and highs. Didn't expect that to so much. Takes your sound to another level. Worth every penny. I have a small room with big speakers the bass was overpowering the rest of the sound. Definitely balanced the frequencies across the whole spectrum and addressed the bass issue. Keeping these!
Pros: They do what they say and not by a little
Cons: Not cheap

Great Product... BUT BEWARE!
Feet are incredible especially for my Sopra No. 3 speakers. Downward firing/ported speakers benefit immensely from increased height in regards to bass respond and control. It's like moving a speaker away from the wall with a rear port. You can hear the difference so worth the price. I highly recommend them. MY BIG COMPLAINT!!! You physically have to loosen the base of your speaker (Focal Sopra's) to get the Focal spikes out on the front two feet. This is really misleading because neither Focal or Isoacoustics states this and both openly advertise this item as compatible. Nowhere is this covered. Having to take apart a speaker to place a aftermarket product is not "compatible" in my book. I'm super upset because I felt as if I was going to damage my new speaker and that honestly ruined the delivery experience for me. With expensive speakers and expensive feet replacements, this really should not be the case. However this is more of a Focal issue, but Isoacoustics too should be making customers aware of this since they advertise this product for the Sopra's.
Pros: Amazing product and build quality. Does make a difference for downward ported speakers.
Cons: Might not have the same acoustic effect on front/rear ported speakers.

Most Bang for the Buck for Performance Upgrade
ROBERT from CLEMMONS, NC on 12/13/2022
Are these expensive for what they are (feet for speakers)? Sure. Are these inexpensive relative to the performance enhancement for funds spent? Absolutely! I have been struggling to make my Revel Salon 2s to disappear in my room after playing with speaker placement. After adding the GAIA feet, I not only got the speakers to disappear, I also benefited by a deeper and more detailed soundstage and instrument placement.

They ARE expensive but they ARE also well worth it!
Josh from PORTLAND, OR on 5/7/2022
I installed two sets of these of my JL Fathom F113V2 Subwoofers in each of my systems. On one system I have the sub on hardwood in a room that opens up to the kitchen and dining area. Without the GAIA I's installed there would be rattles from several spots in this area. Immediately after installing them, I tried out a bass heavy scene and the rattles that I remember from my previous viewings were all gone and it sounded so much cleaner. My other system is fully carpeted, so I also got the optional carpet spikes and I'm happy with the cleaner sounding bass in that room as well. Before I bought these I was not a believer and now I am.
Pros: Cleaner sounding bass, helps remove rattles in a non dedicated living room environment
Cons: Makes moving a heavy sub even more difficult

Sub isolation
Dwayne from Chicago, IL on 4/1/2022
Final and most effective piece in my need for isolation. My new TT was picking up a low frequency feedback isolating the subs was the trick
Pros: They work
Cons: Cost

IsoAcoustics GAIA I
Crutchfield customer from Miami, FL on 3/22/2021
Bought the Gaia I for my Focal Spectral 40th anniversary speakers. Couldn't be happier with the difference in sound. Top end and Midrange are very clear. Bass is punchy and controlled. Originally bought the Gaia II's and the sound was improved with the Gaia II's but both the stance and sound were vastly improved with the upgrade to the Gaia I.
Pros: When matched properly weight wise, the difference is far from subtle.
Cons:

Very happy customer
Crutchfield customer from Mckinney, TX on 10/5/2020
Ziggy was great helping me with this transaction and I could not be happier. Adding these to my loudspeakers really opened them up even more than I could have imagined. Transmission loss to the floor was eliminated and the bass is clean.

Expensive, but they do they job.
Richard from AUSTIN, TX on 4/28/2020
These work. I used them on a Martin Logan Balanced Force 212 subwoofer. The bass was tighter and clearer and there was less transmission of noise through the floor to the rest of the house.
Pros: improve the sound and reduce transmission through the house.
Cons: Price

GAIA I
Neal from Franklin, TN on 12/9/2018
Made a noticeable improvement in my already great sounding Legacy Aeris speakers. I have bare floors and the isolaters did make the music sound clearer and the bass tighter. I can't speak for what the isolaters will do on carpet but improved sound is noticeable on bare floors. Made a more noticeable improvement than a recent cable upgrade.
Pros: Noticeably clearer sound. Well made product and they look great.
Cons: None
