A B&C Coaxial Designed for Professional Speakers and Demanding Projects
The B&C 15FHX76 fits within the logic of professional sound reinforcement coaxial speakers: offering a compact 2-way solution, phase coherent and practical to integrate into a speaker enclosure. By placing the HF motor at the center of the 15-inch cone, this transducer aims for a more stable image and better controlled dispersion than a classic configuration with a separate horn, while maintaining the sensitivity and robustness expected in professional use.
Intended Uses and Target Audience for the B&C 15FHX76
This coaxial speaker is aimed at speaker manufacturers, integrators, and DIY audio enthusiasts looking for a versatile 15-inch driver for applications such as compact front-of-house cabinets, stage monitors, live sound reinforcement, or portable PA speakers where limiting the number of sound sources is desired. Thanks to its high sensitivity and extended bandwidth, it is particularly suitable for systems where midrange clarity and projection are priorities, while maintaining a solid low-end foundation (LF Fs at 40 Hz).
Performance and Design: What Makes the Difference
Low bass/low-mid designed to handle power
The LF section features a 3-inch (76 mm) copper wire voice coil and a dual roll surround, two key elements for mechanical durability and stability at high levels. The exponential cone receives a waterproof treatment front and back, useful for field conditions (humidity, temperature variations, heavy use) and to maintain consistent performance over time.
3-inch HF motor with fiberglass diaphragm
The high-frequency section uses a HF motor with a 3-inch (75 mm) voice coil and a fiberglass diaphragm, a combination focused on reliability and power handling. With a stated HF sensitivity of 107 dB, the 15FHX76 aims for precise and efficient reproduction, especially in contexts requiring good intelligibility (vocals, guitar, brass, snare drum attacks).
Controlled directivity for clearer dispersion
The 60 x 40 deg coverage clearly indicates the goal: to concentrate sound energy where it is needed and limit unwanted projections. This helps better manage the stage, reflective walls, and listening comfort, particularly in medium-sized rooms or installations where dispersion control is critical.
Ferrite: robustness and consistent behavior
With ferrite magnets, the 15FHX76 relies on a proven approach in sound reinforcement: stable motorization, good durability under use, and simple integration into speakers designed for long-term operation. Its size (overall diameter 393 mm) and weight (9.5 kg) correspond to a professional transducer built to last.

Questions frequently asked
Is the B&C Speakers 15FHX76 suitable for use as a stage monitor?
Its 15-inch coaxial design with a central HF driver is suitable for stage monitors and compact live sound reinforcement speakers. The 60 x 40° coverage focuses sound projection into a defined area.
What amplifier power is recommended for this coaxial speaker?
The low-frequency section handles 800 W AES at 8 ohms, while the high-frequency section handles 160 W AES at 8 ohms. Proper crossover filtering is required, as both sections have separate impedances of 8 + 8 ohms.
What is the frequency response of the 15-inch coaxial speaker?
The stated frequency range extends from 40 Hz to 18 kHz. The low-frequency resonance frequency is 40 Hz.
Is the 60 x 40° directivity suitable for a front-of-house speaker?
This 60 x 40° coverage is intended for controlled sound dispersion, useful when energy must be focused towards the listening area. The HF driver has a sensitivity of 107 dB at 1 W / 1 m.
What are the dimensions and weight of the speaker?
The overall diameter is 393 mm with a height of 199 mm, and it weighs 9.5 kg. The low-frequency section features a 76 mm copper voice coil and a double-roll suspension.
