Product Details

B&C 8CX21 8" Professional Coaxial Speaker 100 x 100 8 Ohm

B&C's 8CX21 8" coaxial loudspeaker produces generous amount of low-distortion output despite its compact form factor. The 8CX21 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 400 watts continuous program, which combined with the driver's high efficiency results in very good maximum output.

The 8CX21's ceramic ferrite LF/HF motor, polyester diaphragm HF driver, and FEA-optimized design produce high output and minimal distortion. In addition to the superior articulation and accuracy of coaxially aligned drivers, the 8CX21 requires very little baffle area compared to separate LF and HF components.
