2" Midrange Compression Driver

2″ Midrange Driver
Unique patented Design
118 dB sensitivity 1 W / 1 m
300 Hz Crossover
90 mm Voice Coil
8 or 16 Ohm

The BMS exclusive voice coil technology employs a light weight Copper Clad Aluminium wire wound inside and outsde of the Kapton™ former to improve the heat dissipation, dramtically increasing the acoustic output and reliability of the driver while minimising the power compression.
