Stack Audio AUVA Speaker Isolation Feet
Taxes & Shipping Included
Stack Audio AUVA speaker isolation feet combine rigid support with vibration absorption to enhance your listening experience. These hybrid feet work on both hard floors and carpets, stabilizing speakers while dissipating cabinet resonance before it reaches the floor. By eliminating vibration interference, the AUVAs deliver cleaner sound reproduction with improved clarity and frequency balance. The result is more precise, focused audio that lets your music shine without unwanted coloration or masking.
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.
Enclosed within the AUVA’s precision machined aluminium cases are multiple cells containing particles. 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.Designed and manufactured in the UK
