Evans EMAD Onyx Bass Batter Drumhead – 18" to 26" Sizes

The Evans EMAD Onyx Bass Batter Drumhead is designed for drummers looking for controlled low-end tone, increased attack, and easy customisation of sustain and resonance. With a sleek matte black appearance and single-ply 10mil construction, each Onyx head features the patented Externally Mounted Adjustable Damping (EMAD) system—allowing players to fine-tune their sound by simply swapping damping rings.

Why Choose Evans EMAD Onyx Bass Drumheads?

The EMAD Onyx series is a popular choice among working drummers who need quick and effective control over bass drum tone. Whether you're tuning for studio recording or live performance, the included damping rings let you switch between punchy, tight response or a more open and resonant sound without removing the head. The matte black aesthetic also pairs well with modern drum kits.

Thanks to Level 360 Technology, tuning is more consistent, with a wider pitch range and better contact between the drumhead and bearing edge—ideal for quick head changes and reliable performance under pressure.
