B&C Speakers 15 NW 76

A 15-Inch Neodymium Reference Designed for Modern Sound Reinforcement

The B&C 15NW76 is a 15-inch (38 cm) speaker focused on bass / low midrange, typically sought after when combining impact, clarity, and efficiency within a reasonable speaker enclosure volume. Its architecture features a neodymium magnet motor (lighter) and a design adapted to the demands of current sound reinforcement systems: high power, excursion control, and mechanical components sized to withstand intensive use.

With a recommended enclosure volume of 90 liters tuned to 53 Hz, this model naturally fits into the category of speakers intended for versatile subwoofers and full-range heads where firm bass is expected, capable of cleanly extending into the low midrange, while remaining easy to integrate into a bass-reflex design.

For Which Speakers and Users Is the B&C 15NW76 Intended?

This model is aimed at speaker manufacturers, integrators, service providers, and DIY enthusiasts looking for a 15-inch driver capable of providing the foundation of the mix in sound reinforcement : bass reinforcement, low midrange for a powerful head, or a bass-reflex module oriented towards punch. Its 8-ohm impedance facilitates pairing with many power amplifiers, whether working with a single speaker, pairs, or clusters.

Thanks to its high sensitivity and power handling, the 15NW76 is suitable for applications requiring high output with headroom : concerts, DJs, clubs, fixed installations, or mobile systems where weight and handling matter. The specified frequency response up to 2 kHz also allows for comfortable crossover points depending on the type of horn or driver used above, while maintaining a present low midrange.

Design and Key Points: Power, Control, and Reliability

AES Power and 76 mm Voice Coil: A Solid Foundation

The B&C 15NW76 is rated at 1200 W AES and features a 3.0-inch (76 mm) copper wire voice coil. This combination aims to maintain stability and high-level power handling, especially when the speaker is driven with dynamic programs (kick drum, electric bass, sub-bass) and over long durations.

Excursion and Control: Xmax 8.0 mm

With an Xmax of 8.0 mm and a Qts of 0.22, the 15NW76 performs well in typical sound reinforcement tuned enclosures, where tight and efficient bass is prioritized. Mechanical control is enhanced by a triple roll suspension, designed to maintain good stability when increasing acoustic pressure, while limiting undesirable behaviors at high excursion.

Durability in the Field: Treated Cone and Double Siliconed Spider

The exponential cone benefits from a waterproof treatment front and back, a real advantage in real-world conditions (humidity variations, loading/unloading, outdoor use). The double siliconed spider contributes to the stability of the moving assembly and the repeatability of performance over time, which is essential to maintain consistent sound across multiple speakers in a system.

Bass-Reflex Integration: Recommended Volume and Tuning

The recommendation of 90 liters with a tuning at 53 Hz provides a clear baseline for designing or optimizing an enclosure around this 15-inch driver. It is a relevant starting point to aim for efficiency and impact, with usable bass down to 40 Hz depending on the final design, enclosure, tuning, and crossover management.
