BMS 4554 is a powerful 1.4" 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 minimises the
power compression. The BMS 4554 - 1.4" compression driver is designed for a wide
variety of applications including budget projects requiring 1.4" driver of high
sonic quality. The 4554 offers all the benefits of the patente BMS compression
driver in a 1.4" format, but at much reduced cost.
