Stack Audio AUVA Loudspeaker Isolators Announced

Stack Audio's AUVA speaker stand isolators act "like a natural extension of your speakers" while absorbing vibrations.

Stack Audio's AUVA (audio vibration absorber) loudspeaker isolators are designed to "hold loudspeakers rigidly whilst simultaneously absorbing vibration. In doing so, they combine the advantages of both spikes and compliant isolators, without the drawbacks of either, acting like a natural extension to your speakers".

We are told that AUVAs differ from compliant isolators because, rather than moving and compressing to absorb vibration, Stack's patent-pending particle impact damping technology dissipates vibration whilst holding the speaker rigidly.

The AUVA comprise various materials, including tungsten, to create multiple finely-tuned particle-filled cells enclosed in a precision-machined aluminium case. The manufacturer says that vibrations excite the particles, creating movement and collisions that dissipate the energy virtually instantaneously, while the materials used ensure linear broadband absorption.

Stack Audio adds that maximising the contact between the AUVA cell walls and the particles ensures a high level of vibration can be dissipated, resulting in a more precise rendering of the musical recording. Furthermore, the rigid shell securely holds the speaker while reproducing musical and spatial details precisely.

There are two versions of Stack Audio's UK-designed and made AUVAs to choose from – AUVA 70 (70mm diameter) and AUVA 100 (100mm). They attach via supplied threaded bolts into the existing mounting holes on the underside of your loudspeakers. In addition, the AUVAs are provided with both carpet spikes and protective felt pads for use on solid floors.

The AUVA 70 contains three internal cells for effective vibration absorption, whilst the AUVA 100 has twice the surface area and five cells. The AUVAs can be used with both stand-mount and floor-standing loudspeakers. Stack says the larger size and extra vibration-absorbing capacity of the AUVA 100 are ideal for those who seek the ultimate level of performance from their isolators.

Both sizes are available to order from the Stack Audio website with a 30-day trial period. The Stack Audio AUVA 100 have a £620 RRP (inc VAT) for a set of four and £1,240 for eight. The AUVA 70 costs £420 for four and £840 for eight.
