The BOOM CRD™, or Compound Resonance Driver, offers a versatile system of innovative tools and attachments that simultaneously combine several forms of resonance and vibrational energy generation, transfer, and control. It gives a drum more boom. It enables the drummer, or audio engineer, etc., to customize, enhance, and/or maximize the bass sound and output produced by a drum. It can be applied to the batter or the resonant head, and allows precise control of the airflow escaping the drum and the corresponding back-pressure that the drummer feels. In addition, it may be applied to a speaker cabinet or any other sound-producing, or sound-shaping device. The results are sonically exciting!


The Boom CRD™ functions like a drumhead that you apply to a drumhead. It has a resonance of its own that combines with and multiplies the resonance of the head to which it is applied. This controlled chain reaction provides a bass drum sound that breathes. Because there is no port tube, there is no attenuation of the high frequencies.
