B&C Speakers 15CXN76 4/8 Ohms

A B&C Coaxial Designed for Modern Sound Reinforcement and Compact 2-Way Speakers

The B&C 15CXN76 fits within the logic of coaxial speakers aimed at simplifying the design of high-performance speakers: a single transducer, a more "point source" sound, and easier integration into formats where space is limited. In professional sound reinforcement configurations, this type of solution is particularly appreciated for stage monitors, compact front-of-house speakers, or systems where controlled directivity is desired without multiplying the number of drivers.

Thanks to its neodymium magnet, this model also targets mobile applications: reducing weight without sacrificing power handling, while maintaining an extended frequency response rated from 40 Hz to 18 kHz.

What Are the Most Relevant Uses for the B&C 15CXN76?

This coaxial speaker is primarily intended for speaker manufacturers, integrators, technicians, and DIY enthusiasts who want a 15-inch capable of covering a wide frequency range in a 2-way speaker. It is especially suitable for projects seeking impact in the low end, solid presence in the midrange (vocals, guitars, keyboards), and a high frequency capable of carrying without harshness when filtering and equalization are properly handled.

With a recommended enclosure volume of 100 liters and a tuning of 45 Hz, it naturally fits into a bass-reflex design oriented towards "sound reinforcement": ample bass, good efficiency, and the ability to maintain level over time. The stated 80-degree coverage helps aim for more controlled dispersion, useful both as monitors and front-of-house depending on the baffle geometry and horn/waveguide used.

Coaxial Design, Neodymium Magnet, and Manufacturing Details: What Makes the Difference

Coaxial Architecture: Coherence and Space Saving

The coaxial principle places the high-frequency driver at the center of the 15-inch driver. The result: more aligned output between the low/mid and high frequencies, and simpler integration into compact speakers. This approach is sought after when an efficient 2-way system is desired, with a more concentrated source point and better perceived homogeneity between registers, provided that filtering and phase alignment are carefully managed.

Power Handling and Sensitivity: Built to "Play Loud"

The rated AES power of 800 W (LF) and 160 W (HF) provides a good margin in professional contexts. Combined with a sensitivity rating of 99 dB on the low-frequency section and 105 dB on the high-frequency section (at 1 W/1 m), this configuration aims for excellent efficiency: levels are reached quickly while retaining headroom for transients (snare drum, bass attacks, percussion).

Suspension and Cone: Stability and Heavy Use

The triple-roll LF suspension is designed to promote mechanical control and robustness under sustained use. The exponential cone with waterproof front treatment fits within a logic of speakers intended to operate in real-world conditions (transport, ambient humidity, events), limiting undesirable effects on cone behavior.

Polyester/Titanium Diaphragm: Precision and Projection

On the high-frequency side, the Polyester/Titanium diaphragm aims for a compromise between definition, durability, and projection, to maintain clarity when the system is driven hard. In a well-designed speaker, this translates to better articulation of vocals and clearer detail presence (string attacks, harmonics, cymbals), while maintaining headroom before mechanical saturation.
