Purpose Built For Subwoofers

The AUVA SW is purpose-built to control the powerful, high-amplitude energy produced by subwoofers. It absorbs this vibration at the source to keep the entire system composed and precise.

A well-integrated subwoofer should add depth, scale, and impact without overwhelming the rest of the setup. Proper integration lets the sub handle the low-frequency workload so your main speakers can deliver more openness and detail. By removing the structural vibration that disrupts this balance, the AUVA SW keeps bass tight and controlled so the sub blends naturally with your system, preserving clarity, realism, and the spatial cues that define a stable and natural soundstage.

Three-Stage Hybrid Isolation

Energy-absorbing AUVA pods sit at the top of each isolator. Inside, a tuned particle mass absorbs and disperses vibration, converting it into heat.

The CSA-SW element is a custom silicone absorber that builds on the proven technology of the AUVA EQ, tuned for the vibration characteristics of subwoofers and available in six weight-matched versions for optimal performance.

Precision-machined aluminium housing is shaped to control the CSA-SW’s compliance, ensuring it moves exactly as intended. This precision allows us to push the boundaries of compliance, maximising bass isolation without compromising stability.

Engineered Through Modeling, Refined By Listening

The AUVA SW was partly developed using Finite Element Analysis to model its behaviour under subwoofer-level energy. Twenty-nine design iterations were refined to optimise isolation and energy dissipation, ensuring the engineering delivers tighter low-frequency control. The structure was defined by modelling, with the final refinements made through listening. This process ensures not only cleaner bass, but a more stable, spacious, and natural soundstage.

SPECIFICATIONS

The AUVA SW is tuned to match the weight of your subwoofer. A compliant isolator needs to be as soft as possible to deliver effective vibration control, while still being strong enough to support the load. To achieve this balance, the AUVA SW is available in six weight-matched versions. Each class is designed to operate at its optimal compliance point, ensuring consistent and reliable isolation for subs of any size.
