Historical Context and Positioning in the Range
Within the Evans lineup, the EMAD family has become a benchmark for those seeking a bass drum sound that is immediately "mix-ready." The Heavyweight version takes the concept further with a thicker construction, designed to withstand repeated impacts while maintaining effective resonance control.
Who This Drum/Instrument Is For
This bass drumhead is aimed at intermediate to expert drummers who want a controlled, powerful, and consistent sound, especially in rock, metal, pop, modern funk, worship, and contemporary music. It is particularly suited for setups where a firm low end and a clear attack are desired, even at high volume.
Features and Innovations
Thanks to the EMAD system, damping is easily adjustable via interchangeable external mufflers, allowing adaptation of the bass drum's response to the room, microphone, and playing style. The double ply 20 mil construction improves durability over time and helps stabilize the feel under the beater, providing a more solid and consistent response.
Sound Characteristics
The transparent EMAD Heavyweight emphasizes a clear attack, a generous low end, and better-contained overtones. The double ply enhances the "punch" sensation and promotes a denser sound, while the two muffler widths (13 mm or 18 mm) allow switching from a more open kick to a shorter, more controlled sound without resorting to internal muffling solutions.

Is the Evans BD18EMADHW drumhead suitable for an 18-inch bass drum?
Its 18-inch diameter is designed for a bass drum of that size.
What is the thickness of this bass drumhead?
The construction consists of two 10 mil plies, totaling 20 mil. This thickness is designed to withstand repeated hits and provide a consistent response under the beater.
How does the EMAD damping system work?
