Evans EMAD Onyx Bass Batter Drum Head 20 in.

The EVANS EMAD Onyx bass batter drum head 22" provides drummers unprecedented control over their bass drum sound. The EMAD (Externally Mounted Adjustable Damping) system features two interchangeable damping rings that allow players to adjust attack and focus. By selecting a thinner or wider ring, drummers can maximize punch, resonance, low end or attack. Now available with Level 360 technology, the collar provides easier tuning and a wider tonal range.

Choose Your Sound With Interchangeable Damping Rings

The hallmark of the EMAD series is its adjustable damping system with two removable foam rings. The thinner ring provides focus and resonance without sacrificing punch, while the wider ring maximizes low end and attack. By switching between the two rings, drummers can shape their bass drum tone to match any musical situation or personal preference.

Level 360 Technology for Unparalleled Tuning

The EMAD Onyx incorporates EVANS' revolutionary Level 360 technology, which uses an improved collar shape to allow for easier tuning and a wider tonal range. The Level 360 collar helps the drumhead seat properly, so drummers can achieve a balanced, studio-ready sound with less effort.

Choose From a Variety of Options

The EMAD series offers drum heads in multiple thicknesses, plies and coatings. The EMAD Onyx uses a single ply of 10-mil black film for an extra dark sound with solid punch. Additional options include the original clear and coated EMAD, the double-ply EMAD2, the high-durability GMAD, and the EVANS EMAD Heavyweight for extreme attack. With sizes ranging from 18" to 26", drummers can find an EMAD to suit any bass drum.

Road-Ready Design

In addition to its innovative features, the EMAD Onyx is also built to withstand the demands of touring and live performance. Its 10-mil film and sturdy construction provide durability and consistency show after show. The EMAD Onyx gives drummers a combination of tone-shaping control, road-ready design, and striking black visuals that will make a bold statement on any stage.
