Stack Audio has announced its new range of loudspeaker isolators. AUVA (AUdio Vibration Absorber) feet hold loudspeakers rigidly whilst simultaneously absorbing vibration
The idea is to take the benefits of both spikes and compliant isolators without hitting the drawbacks of either. 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,” said the company.
Enclosed within the machined aluminium cases are multiple cells containing particles (including tungsten). Vibrations excite the particles, creating movement and collisions that dissipate the energy. The aim? An increase in sonic clarity.
At the same time, the rigid shell apparently holds the speaker securely.
The AUVAs are designed and made in the UK by Stack Audio. There are two versions to choose from: the 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.
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-mounted and floor-standing loudspeakers. The larger size and extra vibration absorbing capacity of the AUVA 100 is for those who seek further improved performance.
Both sizes are available now to order from the Stack Audio website (link below). You can give these accessories a try before you commit because there is a 30-day trial period available.
