STACK AUDIO AUVA HAS BEEN DESIGNED TO COMBINE THE ADVANTAGES OF SPIKES AND ISOLATORS

British HiFi brand Stack Audio has announced the introduction of an all-new range of loudspeaker isolators. The Stack Audio AUVA which stands for audio vibration absorber.

STACK AUDIO AUVA

The Stack Audio AUVA are designed to do two things, 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, Theo Stack tells us, like a natural extension to your speakers.

Theo says that “the AUVAs are different from compliant isolators as, instead of moving and compressing to absorb vibration, they use a patent-pending particle impact dampening technology to dissipate vibration whilst holding the speaker rigidly”.

PATENT PENDING PARTICLE IMPACT DAMPENING TECHNOLOGY

Enclosed within the AUVA’s precision machined aluminium cases are multiple finely tuned cells containing particles. Vibrations excite the particles, creating movement and collisions that Theo says dissipate the energy virtually instantaneously. Various materials including tungsten are used to ensure that the broadband absorption is as linear as possible. Maximising the contact between the AUVA cell walls and the particles is designed to ensure a high level of vibration can be dissipated, at the same time, the rigid shell holds the speaker securely.

The AUVAs are designed and made in the UK by Stack Audio. There are two versions to choose from AUVA 70 and AUVA 100. They attach via supplied threaded bolts into the existing mounting holes on the underside of your loudspeakers. The AUVAs are supplied with both carpet spikes and protective felt pads for use on solid floors.

STACK AUDIO AUVA 70 AND 100

The AUVA 70 contains three internal cells for vibration absorption, whilst the AUVA 100 has twice the surface area and 5 cells. The AUVAs can be used with both stand mount and floor standing loudspeakers. 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”.

Both sizes are available now to order with a 30-day trial period.
