The Stack Audio AUVAs help bring your music to life. The AUVAs are designed to do two things: hold loudspeakers rigidly whilst simultaneously absorbing vibration. They combine the best qualities of both spikes and isolators – without the drawbacks of either. Designed to be used on either hard floors or carpets; with the AUVAs direct sound waves are more precisely focused and cabinet vibrations are dissipated before reaching the floor.

Vibrations can distort the sound we hear, causing certain frequencies to be emphasized while others are masked. The AUVAs tackle this issue by preventing vibrations from interfering with the speakers performance. 

Enclosed within the AUVA’s precision machined aluminium cases are multiple cells containing particles such as tungsten powder. 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.
