Description
Stack Audio AUVA 70 is a speaker isolation foot — not an equipment foot. It replaces stock spikes or pads and screws into the existing threaded inserts under the speaker. Machined from solid aluminium with three tuned particle chambers (including tungsten powder). Vibration is converted to heat by particle collisions. The rigid shell keeps the speaker planted. Designed and made in the UK.
Diameter 70 mm, height 30 mm (excluding bolt and spike). About 370 g each (without accessories). Load capacity about 275 kg (per manufacturer). Thread options include M6, M8, M10, M12 and more, with adapters and nuts. Hard floors: pre-fitted felt; carpet: 15 mm or 25 mm spikes. Usually sold in sets of 4 or 8 (8 for a pair of speakers).
Design highlights
- Speaker isolators — replace stock spikes
- Ø70 mm, 3 particle absorption chambers
- Load capacity about 275 kg
- Hard-floor felt or carpet spikes
- Multiple thread adapters
- Made in the UK
Sonic character
Tighter less-blurred bass, clearer mid/highs, surer timing. More spatial detail and stable imaging. Especially clear on suspended wood floors where stock spikes still excite resonance. Not warmer or thinner — it removes vibration returning from the floor.

- The Audiophile Man: accurate imaging and timing; worth trying.
- StereoNET: better separation, less bass blur; floor resonance removed on suspended floors.
- HiFi-Advice: long-term under floorstanders — reluctant to return to stock feet.
