Evans Emad System Bass Pack 20 Inch

Historical Context and Positioning in the Range

For over 60 years, EVANS has established itself as a reference in drumhead innovation, notably with the first synthetic drumhead and iconic series such as EMAD, Hydraulic, and UV1. The EMAD System pack follows this logic: offering a clear, effective, and reproducible solution to meet a central need for drummers, namely precisely controlling the bass drum sound according to style, venue, and recording setup.

Who This Drum/Head Pack Is For

The EVANS EMAD System pack is aimed at beginner drummers who want to quickly achieve a clean and balanced sound, as well as intermediate and advanced musicians seeking a more defined bass drum sound in rehearsals, on stage, or in the studio. It is particularly relevant for styles where the bass drum must remain clear and controlled: rock, pop, metal, funk, gospel, and also for any context requiring a simple and effective mic setup.

Features and Innovations

The EMAD concept is based on a simple idea: allow sustain adjustment without adding pillows or foam inside the bass drum. The transparent EMAD batter head (single ply) comes with two interchangeable damping rings to adapt note length and feel under the beater. The EMAD resonant head complements the set with a 10 cm offset port designed for mic placement, and a peripheral foam ring around the port that helps reduce unwanted overtones and keeps the low end cleaner. The entire set also benefits from EVANS Level 360 technology, designed to improve seating on the bearing edge and make tuning more reliable.

Sound

With its 10 mil films (single ply), this pack favors a direct response and good sensitivity while maintaining a present low end. The EMAD batter head delivers a clearer attack and increased definition, while the ring system allows switching from a more open bass drum to a shorter, more focused sound-ideal for gaining precision in the mix.

The resonant head with offset port facilitates mic capture and contributes to a more controlled projection. The foam ring around the port helps contain unwanted resonances, resulting in a cleaner sound with fewer intrusive overtones. The outcome is a more "finished" bass drum sound, more consistent from one setup to another, and easier to adapt depending on the context.
