Dcm420%2000
Continuous Power Handling
Voice Coil Diameter
Diaphragm Material
Throat Diameter

B&C engineers have been working for the last five years on a family of next generation high frequency devices. Compression drivers are the linchpin of a PA system: operating at wavelengths too small to readily couple with other drivers, they alone have to fight distance and atmospheric losses to deliver concert sound pressure levels to ever larger audiences. 

Enter the DCM420 ring radiator midrange driver, designed from scratch to advance the state of the art. The DCM420’s midrange diaphragm covers 300Hz – 6.0kHz with 112 dB sensitivity (8 Ohm version), and its 100mm voice coil handles 220 watts. All this energy arrives at a 2” throat, from the most compact package that can be designed today.

Brand new materials and thousands of hours of modelling and testing result in lower distortion at higher SPL than has ever been possible before. Consider the new DCM420 for your next design, and enjoy a new standard in fidelity, with the reliability and consistency you expect from B&C.
