Absorbing vibrations reveals more music

The Stack Audio AUVAs help bring your music to life. The AUVAs are designed to do two things: hold loudspeakers rigidly whilst simultaneously absorbing vibration. They combine the best qualities of both spikes and isolators – without the drawbacks of either. Designed to be used on either hard floors or carpets; with the AUVAs direct sound waves are more precisely focused and cabinet vibrations are dissipated before reaching the floor.

Vibrations can distort the sound we hear, causing certain frequencies to be emphasized while others are masked. The AUVAs tackle this issue by preventing vibrations from interfering with the speakers performance. 

AUVA technology

Enclosed within the AUVA’s precision machined aluminium cases are multiple cells containing particles such as tungsten powder. Vibrations excite the particles, creating movement and collisions that dissipate the energy virtually instantaneously. Think of it like throwing a ball into soft sand – the sand absorbs the energy from the ball preventing it bouncing. This patent pending technology enables the AUVAs to remove masking vibrations over a wide frequency range, revealing more of the clarity in the musical recording.

Managing speaker energy

Effective management of speaker energy is crucial for achieving clear and precise playback. By controlling unwanted resonance, we can significantly enhance sound quality, leading to a more accurate and immersive listening experience. While spikes and compliant isolators are commonly used to address vibration, they each come with their own drawbacks.

Spikes

Spikes are often favoured for their ability to anchor the speaker to the floor; however, they can act as conduits for vibration. As energy travels downward from the speakers, it reflects back through the spikes, creating unwanted resonance that disrupts both speaker performance and room acoustics.

Rubber (Compliant Isolation)

Compliant solutions like rubber isolators absorb vibration through movement. While this method is generally more effective than spikes at absorbing vibration, speakers require stability. Excessive cabinet movement can disrupt performance, skewing the soundstage and diminishing playback accuracy.

AUVA

The AUVAs maintain structural rigidity while dissipating energy through its unique multi chambered particle impact dampening system. This innovative approach results in clearer sound, enhanced detail, and improved spatial accuracy, allowing listeners to experience music with greater transparency and realism.

Independent Measurements

Suunniteltu ja valmistettu Isossa-Britanniassa

Our business is rooted in British manufacturing, with all products designed and assembled in-house in the UK. Partnering with local suppliers who share our commitment to quality, we ensure every detail matters—inside and out. From the external finish to the smallest internal feature, we take pride in top-quality products.

AUVA 50, AUVA 70 & AUVA 100

The AUVAs are designed and manufactured in the UK by Stack Audio. There are three versions to choose from – AUVA 50, 70 and 100. They attach via supplied threaded bolts into the existing mounting holes on the underside of your loudspeakers or stand mount. Different thread sizes are available to suit. The AUVAs are supplied either with carpet spikes or protective felt pads for use on solid floors. Choose which option you require at checkout.

The vibration absorbing performance of the AUVAs adjusts with the version and size. The AUVA 50 contains 2 internal cells for effective vibration absorption. The AUVA 70 has 3 cells and the 100 has 5. Both the AUVA 70 and 100 include a central particle filled chamber for extra absorption capability. All AUVAs can be used with both stand mount and floor standing loudspeakers.

Which AUVA is best for my speaker?

All AUVAs can be used with both stand mount and floor standing loudspeakers. The 70 contains 3 internal cells for superior vibration absorption, whilst the AUVA 100 has twice the surface area and 5 cells. The larger size and extra vibration absorbing capacity of the AUVA 100 is for those who seek the ultimate level of performance from their isolators.

Should I use spikes or felt pads?

The Spike option for the AUVAs is purely for carpets, this ensures that the rigidity that is core to the AUVAs design philosophy is maintained. Felt pads are optimal for any type of hard floor.

Do the AUVAs work on carpets?

Yes, removable spikes are included. There are 3 removable spikes for each isolator.

Do the AUVAs work on hard floors?

Yes, protective adhesive felt pads supplied with the AUVA isolators for hard floors. Once fitted they cannot be removed but they feature holes to also allow carpet spikes to be fitted subsequently

Do the AUVA Absorbers have to face in a specific direction?

No, the orientation of the absorbers has no correlation to its performance.

What thread sizes are available with the AUVA isolators?

We stock a vast variety of threads. If you do not know which thread you require, please contact us with details of your loudspeakers.
