Overview

B&C 5NSM38-8 5" Professional Neodymium Sealed Back Midrange 8 Ohm

B&C Speakers' 5NSM38-8 5" sealed back midrange produces high efficiency midrange response from 300 to 3,500 Hz with remarkably low distortion. With a non-resonant cast aluminum rear chamber, the 5NSM38-8 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 5NSM38-8 is the ideal midrange for use in high output direct radiation and front loaded horn 3-way speaker systems.
