The Evans EMAD Onyx bass drum head combines low-end punch with precision attack control in a matte black finish. Built on a single 10mil ply, this coated head uses the EMAD system's foam damping rings to shape attack, focus, and sustain. The Onyx treatment delivers a more defined beater strike with shorter sustain than standard clear heads, adding darker tonal character that mirrors the visual aesthetic while maintaining the focus and low-frequency response EMAD heads are known for across stages and studios.

The 10mil single-ply construction provides a balanced foundation between resonance and control, with the included EMAD foam rings offering variable damping configurations. Level 360 Technology ensures even seating and consistent tension across the bearing edge, improving tuning stability and head longevity. The coated matte black surface enhances the darker tone profile while reducing overtone complexity. This 22-inch diameter head fits standard bass drum shells, with the removable external damping rings allowing quick tonal adjustments between songs or sessions without retuning the entire kit.
