B&C 5NSM38 5-Inch Speaker Driver - 110W RMS, 16 Ohm

The B&C 5NSM38 5-Inch Speaker Driver simplifies cabinet assembly and efficient thermal transfer to the air. The 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.
