B&C 6 NSM 51 8 LF Driver
- 500 W Continuous power handling
- 2.0 in (51 mm) Voice coil diameter
- Neodymium Ring Magnet material
For simplified cabinet assembly and efficient thermal transfer to the air, our NSM series of sealed back midranges feature a cast aluminum sealed chassis, high strength neodymium motor, and large internal volume for good low frequency performance. Large voice coils provide power handling, while careful selection of suspension and cone components results in exceptional sensitivity. These dedicated narrow-bandwidth midranges offer the lowest distortion at given output of any midrange available.
