The Compact GAIA Neo for Slim Towers up to 70 Pounds
The IsoAcoustics GAIA III Neo is sold as a set of four, in black or dark chrome, and every speaker takes one set. It carries a floorstanding speaker or subwoofer of up to 70 pounds. The feet screw into the inserts the factory spikes came out of, and the height adjusts once the speaker is in place.
A floorstander pushes its own energy into the floor, and the floor pushes it back into the cabinet. IsoAcoustics designs the GAIA Neo to manage that energy inside the foot. The housing is fixed to the speaker, and only the lower isolator touches the floor.
The Second-Generation GAIA, Sized for Slim Towers
Fit, Load and Materials
A set of four GAIA III Neo carries 70 pounds, so each foot handles 17.5. No minimum is published. A foot carrying far less than its rating never reaches its working range. It is the lightest Neo rung; a heavier cabinet steps up to the GAIA II Neo. The IsoAcoustics online weight selector sorts this by weight.
Each foot is 2.2 inches across and 1.8 inches tall, in a metal housing finished in black or dark chrome. Turning the lower ring moves it up to 0.34 inches, so you level the speaker once it is standing. Three thread adaptors are included: M8-1.25, M6-1.0 and 1/4 inch-20. Other sizes: see the GAIA thread-size guide.
An O-ring seats the housing flush against the speaker base. The lower isolator pivots to stay in full contact on a floor that is out of true. Floor sliders with felt pads come in the box, so the speaker slides into place on carpet or hardwood before you level it.
What Reviewers Are Saying
Popular Science named the GAIA Neo speaker isolation feet a winner in its 2025 Audio Awards, with reviewer Tony Ware writing that they “rein in energy loss and unleash imaging.”
Who Is the GAIA III Neo Best For?
- You own slim floorstanders of 40 to 70 pounds each — a set of four GAIA III Neo carries them inside the working range
- Your floor is not perfectly level — the lower ring adjusts 0.34 inches per foot with the speaker in place, and the isolator pivots to stay in contact
- You move your speakers to tune the room — the included sliders let the cabinet slide into position on carpet or hardwood
- You want the feet to look built in — the O-ring seats the housing flush to the base, in black or dark chrome to match the cabinet
- Your speakers weigh more than 70 pounds each — the GAIA II Neo carries 120 pounds a set
How Do You Set Them Up?
Unscrew the factory spikes and match the thread. One side of the adaptor goes into the speaker and the other into the Neo housing. Screw each foot in until the O-ring seats flush, with the logo facing your seat. Set the sliders under the feet, push the speaker into position, then tilt one side at a time to remove them.
Turn each lower ring to level the cabinet. On thick carpet, the matching carpet discs give each foot a solid surface to stand on. Check that the logos still face forward, and play.
Pairs Well With
What most GAIA III Neo owners shop next.
- Speaker stands — get the tweeters to ear height before you isolate
- Floor and carpet protection discs — a firm footing on carpet or a soft floor
- Speaker cables — the next link in the chain after the speakers are settled
- Speakers — the bookshelf and desktop models these are made to sit under
Frequently Asked Questions
How many do I need?
Four per speaker, one at each corner, matching the spikes they replace. The GAIA III Neo is sold as a set of four, so order one set per speaker or two for a stereo pair.
Which GAIA Neo fits my speakers?
Go by the weight of one speaker: GAIA III Neo up to 70 pounds, GAIA II Neo up to 120, GAIA I Neo up to 220. The IsoAcoustics online weight selector settles borderline weights in a few seconds.
Will they fit my speaker's threads?
Adaptors for M8-1.25, M6-1.0 and 1/4 inch-20 come in the box. If your speaker uses another size, IsoAcoustics supplies other adaptors. Its thread-size guide shows how to measure the insert.
Can I use them on carpet?
Yes. The sliders in the box move the speaker into place on carpet. On thicker carpet or an underpad, IsoAcoustics recommends its GAIA III Neo carpet discs, which give each foot a solid surface.
How does the height adjustment work?
Rotate the lower ring of each foot to raise or lower it by up to 0.34 inches. The adjustment does not change the isolator's alignment, so you can level a speaker or add a little tilt after it is standing.
