AUVA EQ and AUVA 50 FROM STACK

15th August 2023

Stack Audio has announced the AUVA 50 loudspeaker isolators and the all-new AUVA EQ system isolators

Let’s start with the EQs, shall we? These are aimed at isolation general components in your HiFi chain. Like the AUVA speaker feet that I reviewed and like an awful lot, these EQ are also Particle Impact Damping isolators. The same tech is used but alongside CSA (Custom Silicone Absorber), a new purpose-designed deformable suspension that provides Compliant Damping.

The rigid machined-aluminium shell of the AUVA EQ is designed to sit underneath Hi-Fi equipment in direct contact with the case. The silicone absorber sits on the Hi-Fi shelf or rack.

As such, the case of the Hi-Fi equipment is directly coupled with the AUVA chamber of the EQ but de-coupled (or isolated) from the Hi-Fi shelf via the CSA suspension. They are compatible with most Hi-Fi equipment weighing 0.3-60kg/0.66-132lbs.

I have already reviewed the AUVA 70 and 100 feet. These are lower cost models. Like the 70s and 100s, the 50s are designed to do two things: hold your loudspeakers rigidly whilst simultaneously absorbing vibration.

They do the same job as the 70s and 100s but, being of lower cost, there’s just a little less absorbing tech in there. Hence the lower price.

They are available to order from the Stack Audio website in sets of three or four with a choice of felt pads or spikes and a wide choice of fixing sizes to suit most loudspeakers.

The feet are compatible with the majority of speakers up to 275kg/606lbs.

Set of eight is £367.50 (+VAT).
