AUVA SW FROM STACK AUDIO
11th December 2025

New from Stack Audio is the AUVA SW, a purpose-built isolator designed to sit underneath subwoofers
At the first point of contact with the subwoofer, each isolator features an AUVA particle impact damping chamber inside an aluminium pod. In the chamber, a tuned mass of particles absorbs and disperses vibration, converting kinetic energy into heat.

Directly attached to the AUVA pod is a Custom Silicone Absorber (CSA) insert designed to match the subwoofer’s weight. Building on the AUVA EQ system isolators, this version features 8 “prongs”, tuned specifically for the energy profile of subwoofers.

Each case is machined from solid aluminium into a rigid, braced housing which is carefully shaped to guide the CSA and prevent it from buckling.

Stack Audio’s AUVA loudspeaker isolators are designed to keep speakers rigid. The AUVA SWs are different. Subwoofer energy is omnidirectional, producing long-wavelength vibrations. The SW’s target this specific low-frequency energy, decoupling the subwoofer from the floor.

A height-adjustable silicone/metal pad is available for added stability. Alternatively, for subwoofers with removable feet or threaded inserts, optional adapters are available.

Diameter: 50mm | Height: 35.4mm | Weight: 120g, each. Available in six CSA weight ratings, the AUVA SW is priced at £324 (per set of 4).
