B&C Speakers 15HCX76

A B&C Coaxial Designed for Compact Systems with High Intelligibility

The 15HCX76 fits within the "point source" approach favored by coaxial solutions: combining low/mid and high frequencies into a single transducer to reduce phase issues, simplify integration, and achieve a more stable sound image both on and off axis. In a product range aimed at sound reinforcement, this 38 cm coaxial format targets a highly sought-after compromise: the density and foundation of a 15-inch driver, with an HF section capable of delivering the presence and definition needed for vocals and amplified instruments, all within a controlled footprint.

Intended Uses and User Types

This coaxial speaker is particularly suitable for DIY speaker designers, manufacturers, service providers, and installers who want to build a compact yet powerful 2-way speaker: stage monitors ("wedges"), front-of-house point source speakers, nearfield systems with controlled coverage, or versatile speakers for bars/concerts and rehearsal rooms. With a stated frequency response from 40 Hz to 18 kHz, it can serve as the foundation for a robust full-range speaker, with or without subwoofer reinforcement depending on the desired level and enclosure tuning.

Architecture, Materials, and Key Design Features

15-inch coaxial + 1.3-inch motor: coherence and space saving

The coaxial principle aligns the acoustic centers of both drivers, promoting better perceived temporal coherence and a more natural transition between midrange and high frequencies, especially useful for vocals. It also offers practical advantages: a single main cutout, a simplified front baffle, and easier integration into compact enclosures where a separate horn would require more volume and placement constraints.

Neodymium magnet: performance and lightweight

The neodymium magnet helps keep the total weight at 5.6 kg, an asset whenever the speaker needs to remain portable (stage monitors, mobile systems) or when load on structure and rigging must be limited. In a sound reinforcement context, this also allows for building lighter tops without sacrificing impact.

Titanium diaphragm and HF motor: precision and projection

The HF section, featuring a titanium diaphragm, is designed for clarity and attack, useful to maintain definition at high levels. Combined with a stated HF sensitivity of 107 dB (1 W/1 m), it aims for clear reproduction of transients (snare drum, guitar attacks, vocal consonants) in stage or amplified sound contexts.

LF components focused on durability: triple-roll suspension and treated cone

The low/mid driver benefits from a "triple-roll" LF suspension, designed to handle excursion and mechanical stability as levels increase. The exponential cone with waterproof treatment on the front side is an advantage for real-world use conditions (transport, moderate humidity, stages), improving the membrane's resistance to common wear and tear.

Specified directivity: 60 x 40 degrees (with horn mounted)

The indicated coverage of 60 x 40 degrees with the horn mounted in front of the motor allows for more controlled high-frequency dispersion, useful to limit reflections (walls/ceiling) and focus energy on the listening area. This is an important factor for monitors and small to medium rooms where projection control conditions intelligibility.
