Evans BD18EMADCW - EMAD COATED 18

Historical Context and Positioning in the Range

The EMAD is part of modern bass drum heads designed to offer immediate control of the sound without relying on internal solutions (blankets, foams, pillows). Its interchangeable external muffling system positions it as a highly appreciated choice among drummers who want a bass drum ready for both stage and studio, with quick adjustments depending on style, venue, or recording setup.

Who This Drum/Instrument Is For

This head is aimed at beginner to advanced drummers looking for an easy-to-control bass drum with present lows and a clear attack. It is especially suitable for contexts where a readable kick in the mix is desired (amplification, in-ear monitors, recording), and adapts very well to Rock, Fusion, and Jazz aesthetics by simply adjusting the muffler to achieve more or less openness.

Features and Innovations

The core of the EMAD concept relies on two external mufflers (attenuators) of different widths, which can be quickly mounted and swapped. The 13 mm model allows the head to breathe more for a more open feel and a more natural projection, while the 18 mm tightens the sustain and enhances the sense of control, useful when a focused low end and a more "compact" response are desired. This system affects not only the timbre but also the pedal response, making the attack more predictable and stabilizing dynamics, even at low strike levels.

Sound

With its single ply 10 mil construction and textured finish, this EMAD maintains good sensitivity: it responds to nuances, allows touch work, and preserves true dynamics even without hitting hard. The external muffling then sculpts the head's behavior: you get a bass-rich attack that can be aggressive and precise for modern contexts, or more diffuse and rounded if a more enveloping low end is sought.

The resonance is described as warm, with an enormous low-end response, helping the bass drum fill the space without becoming overwhelming. In practice, the EMAD facilitates a "mix-ready" sound: solid lows, harmonic control, and a clear strike feel that highlights footwork, whether in the studio or on stage.
