B&C Speakers 15 PS 76

A Performance-Oriented 15-Inch Speaker for Sound Reinforcement Setups

The B&C 15PS76 is a 15-inch (38 cm) driver designed for sound reinforcement applications where level, impact, and mechanical durability are required. Its 15-inch format makes it a natural choice for front-of-house speakers, powerful stage monitors, or horn/bass-reflex loaded systems, when the goal is to achieve fast bass and present low-midrange without sacrificing endurance. With a recommended enclosure volume of 110 liters tuned to 45 Hz, it easily fits common cabinet or full-range head volumes while maintaining predictable behavior under heavy use.

Who Is This Speaker For and What Are Its Uses?

This model is primarily aimed at speaker builders, integrators, contractors, and DIY audio enthusiasts seeking a solid foundation for a bass/midrange section. Thanks to its frequency range (40 Hz to 2 kHz), the 15PS76 can be used:

as a woofer in a 2-way system (with a compression driver and appropriate crossover), as a low-midrange driver in a 3-way system, or as bass reinforcement for speakers that need to remain punchy and clear at high volume. Its high sensitivity helps achieve significant output with controlled amplification, which is especially appreciated in mobile setups, stages, multipurpose rooms, or fixed installations.

Design and Key Elements: Stability, Control, and Efficiency

The 15PS76 emphasizes power handling and excursion control, two essential factors for maintaining clean bass at high levels.

76 mm Copper Voice Coil: Thermal Endurance and Control

The 76 mm (3-inch) copper voice coil is sized to withstand long and demanding sessions. This design promotes good stability under sustained operation, with behavior suited to the heavy demands typical of sound reinforcement.

Triple Roll Suspension and Double Silicon Spider: Mechanical Durability

The triple roll suspension helps maintain more linear movement and better control of the cone during large excursions. Combined with the double silicon spider, it ensures solid centering of the moving assembly, improved resistance to mechanical fatigue, and sustained performance over time, even at high levels.

Exponential Cone: Impact and Projection

The exponential cone is a common choice for speakers designed to retain attack and presence in the low-midrange. This helps achieve a more "projected" sound and clearer reproduction of impacts (kick drum, bass, toms) in the mix, especially when the speaker operates within its comfort zone.

Ferrite Magnet: Balance Between Efficiency and Robustness

The ferrite magnet offers a proven solution, valued in professional environments for its durability and consistency. Weighing 8.7 kg, the 15PS76 remains a substantial component to integrate into a stable enclosure, especially if the speaker is intended for transport.
