1.5" Midrange Neodymium Compression Driver

1.5″ Midrange driver
Unique patented design
118 dB sensitivity 1 W / 1 m
300 Hz crossover
90 mm voice coil
8 or 16 Ohm

BMS 4595ND-mid 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 annular diaphragm covers the frequency range between 300 and 7.000 Hz with a smooth, linear response. The large diaphragm excursion of max. +/-0.8 mm results in high output and increased power handling up to 1.300 W peak.
