EXD Bass Drum Head External Damping

The EXD Bass Drum Head from Bonham Drumheads features external damping (EXD) via an attached foam ring that reduces overtones and controls sustain directly at the edge of the head. The foam ring can be removed if you prefer a more open, resonant sound — giving you flexibility to dial in exactly the kick tone you need.

Whether you want a tight, controlled thud for recording or a more open sound for live performance, the EXD head adapts to your playing environment without the need for additional muffling materials inside the drum.

The EXD Bass Drum Head is essentially a twin-ply oil-filled design, similar to the HYD, but with external damping control. The attached foam ring sits on the outside edge of the head, allowing you to manage overtones and sustain without internal muffling. Remove the foam ring whenever you want a more open, resonant response. This dual-approach design gives you the tonal flexibility of a HYD with the convenience of adjustable external damping — ideal for drummers who switch between tight studio tones and fuller live sounds.
