Key Features:
B&C 6NSM51-8 6" Professional Neodymium Sealed Back Midrange 8 Ohm
B&C Speakers' 6NSM51-8 6" sealed back midrange produces high efficiency midrange response from 300 to 6,000 Hz with remarkably low distortion. With a non-resonant cast aluminum rear chamber, the 6NSM51-8 can be easily installed into enclosures without the need for additional isolation. The motor system is powered by a high energy neodymium ring magnet for low weight and high efficiency. Treated with a waterproof coating, the naturally damped paper cone keeps unwanted resonances under control for smooth and accurate response, even when used in harsh conditions. B&C's NSM series dedicated narrow-bandwidth midranges offer the lowest distortion at given output of any midrange available. The 6NSM51-8 is the ideal midrange for use in high output direct radiation and front loaded horn 3-way speaker systems.
