BMS 4550 is a powerful 1" professional compression driver that delivers outstanding sonic quality in a small package. It has an exceptional dynamic range and produces even the most complex music signals with depth and definition. The BMS exclusive voice coil technology employs a light weight Copper Clad Aluminium wire wound inside and outside of the Kapton™ former to improve the heat dissipation, dramatically increasing the acoustic output and reliability of the driver while minimises the power compression.
The BMS 4550 - 1" compression driver is designed for a wide variety of applications in high quality, high power professional reinforcement systems and stage monitors where low crossover frequency is needed.
