B&C Speakers 15CXN88

A Neodymium Coaxial Designed for High-Efficiency Compact Systems

The B&C 15CXN88 fits within the logic of modern coaxial speakers aimed at combining power, compactness, and diffusion coherence. The principle is simple: align the high-frequency emission with the woofer within the same transducer to achieve a more homogeneous response and a "single block" sound image sensation compared to some traditional setups.

With its neodymium magnet, this model clearly targets designs where weight and size matter: portable sound reinforcement speakers, high-performance wedges, or versatile tops, while maintaining the power handling standards expected in professional environments.

Intended Uses and Profiles

This coaxial speaker is aimed at speaker manufacturers, integrators, rental companies, technicians, and demanding DIYers looking for a transducer capable of covering a wide frequency range with controlled directivity. It is particularly suitable for projects where limiting the number of sources (and thus interactions) is desired while maintaining a high level of performance.

Thanks to its specified frequency response of 40 Hz to 18 kHz, the 15CXN88 can be considered as the basis for a compact two-way speaker (with appropriate crossover), for live sound reinforcement, powerful stage monitoring, highly dynamic nearfield systems, or front-of-house speakers in point source configuration. Its efficiency helps achieve volume with controlled amplification, a key point when seeking impact and clarity.

Design and Key Points: Control, Mechanical Strength, and Articulation

Coaxial: Phase Coherence and More Uniform Coverage

The coaxial architecture of the 15CXN88 combines a 15-inch woofer and an HF section, with a specified 80deg coverage. In practice, this type of design is appreciated for producing a more "centered" dispersion, useful when a speaker needs to remain intelligible off-axis and maintain a stable sonic signature in various listening positions (stage monitor, front, compact side fill).

Voice Coils and Materials: Handling Power Without Sacrificing Definition

The woofer section features a 3.5-inch (88 mm) copper wire voice coil, designed for thermal endurance and stability at high levels. The tweeter section features a 3-inch (75 mm) voice coil with a polyester/titanium diaphragm, a choice aimed at a good balance between precision, durability, and behavior in the upper spectrum.

Woofer Behavior: Tuning, Excursion, and Control

With a resonance frequency Fs (LF) of 40 Hz and a Qts of 0.25, this model is typically intended for serious enclosures where tuning and cabinet volume are optimized to achieve clean and controlled bass. The Xmax of 8.5 mm and the dual-roll surround contribute to excursion management to preserve impact and limit distortion when levels increase.

Reliability in Real Conditions: Treated Cone and Intensive Use

The exponential cone benefits from a waterproof treatment front and back, a valued feature for speakers expected to operate in varied conditions (transport, humidity, stages, outdoor events). The goal is to maintain consistent performance and better durability over time while retaining the responsiveness necessary for dynamic reproduction.
