Features :
- 1.4" Driver for budget Projects
- Unique Patented Design
- 113 dB sensitivity 1 W / 1 m
- 1.3 kHz Crossover
- Extended high frequency response up to 20 kHz
- Small Size and low Weight
- 44.4 mm Sandwich in- and outside Voice Coil
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 minimising 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 patented BMS compression driver in a 1.4" format, but at much reduced cost.
