Product Details

B&C 12FCX76 12" Professional Coaxial Speaker 80 x 80 8 Ohm

B&C's 12FCX76 12" coaxial loudspeaker produces generous amount of low-distortion output despite its compact form factor. The 12FCX76 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 700 watts continuous program; combined with the driver's high efficiency, this results in very good maximum output. The 12FCX76's large-format HF compression driver permits an exceptionally low crossover point of 1,200 Hz, which offers a more consistent directivity transition from LF cone to HF horn.

What's the optimum sealed and ported cabinet configurations to get maximum low end extension from these drivers?

Asked by: Zdog124
I would recommend a gross volume of 1.5 cubic feet with a single dual flared 4" port that is 6-1/2" long for a tuning frequency of 52 Hz. This driver will not work very well sealed unless it is a dedicated mid/tweeter crossed above 250 Hz.
