RDacoustic EVO-3

EVO-3 Anti-Resonance Pads are precision isolation supports designed to reduce unwanted vibrations in high-performance audio systems. Using a hardened multi-layer metal body and freely moving ceramic or zirconium spheres, EVO-3 pads improve clarity, spatial definition, bass control, and overall musical coherence. Available in two tuning options to match tube or solid-state electronics.

EVO-3 Anti-Resonance Pads

Precision vibration control for audio components and loudspeakers

EVO-3 Anti-Resonance Pads are the result of more than three years of focused development, testing multiple geometries and material combinations to address one problem: uncontrolled vibration inside audio systems.

Each EVO-3 pad is machined from high-quality duralumin, finished with a double layer of copper and nickel. The nickel surface is further hardened through nitriding at 600 °C, creating a rigid, durable structure. The upper and lower sections are mechanically separated by three ultra-precise hardened spheres, each free to move within its own polished spherical housing.

This construction allows the pad to mechanically decouple components from ambient and self-generated vibrations, preventing vibrational energy from re-entering sensitive electronics or loudspeaker cabinets.

Installation is straightforward. EVO-3 pads are placed directly under the chassis of the component, not under rubber feet. Typically, three or four pads are used under electronics, while four pads are recommended for speakers. Each pad supports loads up to 100 kg.

Two Tuning Options

EVO-3 pads are available with two different sphere materials, allowing users to fine-tune system behavior based on equipment type and sonic preference.

Silicon Nitride Ceramic Spheres

  • Emphasize bass weight and fullness

  • Increase tonal density and smoothness

  • Enhance spatial flow and organic cohesion

  • Particularly well suited to tube amplifiers

This option favors body, calmness, and a more relaxed presentation, while still improving clarity and separation.

Zirconium Spheres

  • Enhance midrange articulation and high-frequency precision

  • Improve speed, attack, and spatial focus

  • Deliver a lighter, more open, and more defined presentation

  • Particularly well suited to solid-state (transistor) amplifiers

Zirconium offers sharper contours, greater air, and increased placement accuracy within the soundstage.

Audible Results

Independent reviews consistently report improvements in:

  • Bass control and articulation

  • Clarity and separation of instruments

  • Vocal transparency

  • Dynamic responsiveness

  • Soundstage stability and spatial definition

Listeners describe EVO-3 pads as increasing musical focus without artificial coloration, allowing recordings to sound more confident, structured, and emotionally engaging.

Why Vibration Control Matters

Vibrations subtly affect electronic components and loudspeakers alike. In high-resolution audio systems, even small mechanical disturbances can blur timing, reduce micro-detail, and collapse spatial cues.

By allowing controlled micro-movement instead of rigid coupling, EVO-3 pads prevent vibrational energy from reflecting back into the system. The result is cleaner signal behavior, improved spatial perception, and greater retrieval of low-level musical information.

Simply put, details carry emotion, space, and realism. EVO-3 pads are designed to preserve them.
