Overview

B&C 8CXN51 8" Professional Neodymium Coaxial Speaker 100 x 100 8 Ohm

B&C's 8CXN51 8" coaxial loudspeaker produces generous amount of low-distortion output despite its compact form factor. The 8CXN51 offers resolution and accuracy that are suitable for professional "fill" loudspeakers, stage monitor wedges, studio monitors, or high-efficiency home audio systems. Power handling is 500 watts continuous program, which combined with the driver's high efficiency results in very good maximum output.

The B&C 8CXN51 8" coaxial speaker's optimized driver alignment delivers the coherency and focus expected from a point source design. In addition to this superior articulation and accuracy, the 8CN51 requires very little baffle area compared to separate LF and HF components.
