Test Bench: B&C Speakers 8NSM64 Closed-Back Midrange
The 8” 8NSM64 is a rather unique new pro sound midrange driver from B&C Speakers. It’s a closed-back midrange! Closed-back midranges are often associated with cheap speakers because by using a frame with no relief holes in the back, you don’t have to build a midrange chamber. In this case, the 8NSM64 is a very high-power handling (500 W continuous) 8” midrange for professional PA applications, with a reasonable volume that can be damped with absorption material.
