BMS 4555 is a powerful 1.5″ professional compression driver that delivers outstanding sonic quality in a small package. 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 minimising the power compression.

The BMS 4555 – 1.5″ compression driver is designed for a wide variety of applications including budget projects requiring 1.5″ driver of high sonic quality. The 4555 offers all the benefits of the patented BMS compression driver in a 1.5″ format, but at much reduced cost.
