Each AUVA SW is matched to the weight of the subwoofer so the compliant element operates at its ideal point. This tuned behaviour allows the isolator to remain stable under heavy bass output while delivering the highest level of vibration control.

Optimal load (per set of 4)

AUVA SW isolators are available in the most common thread sizes used for subwoofers. Adapter plates come as standard for models that don’t use threads, allowing the isolators to sit directly beneath the subwoofer with proper support and stability. Both the adapter plates and the thread fixings allow for small height adjustments during setup.

During testing, we found that the AUVA SWs performed optimally without spikes even when used on carpet. If you would still like to use spikes to protect your carpet, please contact us directly.
