Evans Heads BD18EMADONX 18-Inch EMAD Onyx Bass Drum Heads

The EMAD series bass drum head is named for the externally mounted adjustable damping system. This system allows each player to control the attack and focus of the drum head by choosing one of two removable foam damping rings. Choosing the thinner foam ring allows for punch and focus without sacrificing resonance, while choosing the wider foam ring maximizes the low end and attack of any bass drum. The EMAD system is available in a variety of options including single and two ply, and clear and coated versions to accommodate each drummer's preferences.

Evans is now offering the EMAD series of bass heads with its revolutionary Level 360 technology. With Level 360, Evans has made it easier to tune and get a wider tonal range from your drums than ever before. Applying this new collar shape to our EMAD bass drum head allows it to seat itself properly and in turn provides a head that is easy to tune and a sound that is studio ready.

The EMAD line is comprised of a variety of options with varying thicknesses, plies, and coatings. The original EMAD is comprised of a single 10 mil ply and is available in clear, coated, and the Evans Onyx choices. The EMAD2 is made up of a 6.5 mil ply and a 10 mil ply for added durability and is available in a clear option. The GMAD series takes the single ply construction of the EMAD and adds extra strength by using a 12 mil ply. The Evans EMAD Heavyweight rounds out the line with 2 clear high-performance 10 mil plies. The EMAD Heavyweight is designed to withstand heavy hitting and provide maximum attack.
