B&C 15FHX76 – 15″ High-Output Ferrite Coaxial Driver

The B&C 15FHX76 is a robust 15-inch coaxial loudspeaker engineered for professional audio applications where high output, reliability, and full-range clarity are essential. Combining a 15-inch low-frequency driver with a 3-inch high-frequency compression driver in a single ferrite motor assembly, this coaxial delivers true point-source projection and coherent sound from a single compact unit. Ideal for compact PA systems, stage monitors, and installed sound environments, the 15FHX76 is designed to handle demanding professional use without compromise.

Its ferrite-based design balances performance and cost-effectiveness while offering excellent low-end authority and high SPL output. The 15FHX76’s coaxial configuration eliminates phase discrepancies and reduces signal-imaging artefacts, making it an ideal choice for applications requiring accurate full-range audio reproduction.

Design and Construction

The low-frequency section incorporates a 76 mm (3-inch) copper voice coil wound on a fibreglass former, coupled with a waterproof-treated paper cone to ensure durability and reliable performance under high load. A double silicon spider, high-excursion design and mechanically robust surround allow the driver to handle extended high-power operation without loss of fidelity.

The high-frequency section uses a 75 mm (3-inch) aluminium voice coil with a titanium diaphragm delivering high-transient resolution and accurate clarity at distance. The modified exponential horn flare improves acoustic loading and provides controlled coverage across the listening area.

The integration of LF and HF units in a single ferrite motor assembly reduces enclosure size and weight while maintaining outstanding output performance and extraordinarily low distortion. The 15FHX76 is engineered for both touring and permanent installation environments, where consistent, high-output audio is critical.

An aluminium demodulating ring is included in the motor structure to suppress modulation distortion, ensuring clean, linear output even at sustained high power levels.

Performance and Applications

Rated at 800 W continuous program power for the LF section and 160 W for the HF section, the 15FHX76 provides substantial headroom for professional applications. Its frequency response ranges from 40 Hz to 18 kHz, with a recommended crossover point at 1.2 kHz, enabling smooth integration between the LF and HF components.

Applications include:

• High-output stage monitors for live performance
• Compact PA systems requiring punch and clarity
• Fixed installation in venues with high SPL demands
• Outdoor systems needing rugged, weather-resistant components

The coaxial design eliminates phase misalignment and lobing, resulting in improved real-time intelligibility and consistent coverage. System designers and sound engineers benefit from the driver’s reliable performance in high-pressure environments, making it a versatile solution for various professional audio setups.
