B&C Speakers 12 HPL 64

A 12-inch Driver Designed for Modern Sound Reinforcement Demands

The B&C 12HPL64 fits the spirit of professional drivers intended for PA speakers where efficiency, power handling, and lightweight are sought. With its neodymium magnet and performance-oriented design choices, it responds particularly well to the constraints of mobile systems (portable speakers, monitors, compact stacks) without sacrificing low-mid impact or clarity.

Who Is It For and What Are Its Uses?

This transducer targets speaker manufacturers, integrators, and demanding DIY enthusiasts who want to build a speaker capable of playing loud and clean. Its "low/mid" positioning makes it an excellent choice as a 12-inch front driver for a full-range speaker supported by a high-frequency driver, or as a dedicated low-midrange driver in a 3-way configuration. Thanks to its high sensitivity, it is also suitable for projects aiming to maximize sound level with reasonable amplification.

Design and Performance: Efficiency, Control, and Easy Integration

A Neodymium Motor to Reduce Weight Without Losing Dynamics

The neodymium magnet directly contributes to the compactness and low weight of the speaker while promoting a lively response and good "punch" feel. This is a tangible advantage for speakers intended to be frequently moved or to optimize the total weight of a system.

64 mm Voice Coil: Power Handling and Thermal Stability

The B&C 12HPL64 is rated at 400 W AES at 8 Ohms. Its 64 mm voice coil with aluminum wire aims to balance moving mass and heat dissipation to maintain a responsive response while enduring the demands of sustained PA use.

Triple Roll Suspension and Exponential Cone: Low-Midrange Articulation

The triple roll suspension is designed to support excursion while maintaining good centering and a consistent response. Combined with an exponential cone and a single spider, it contributes to clear reproduction in the critical range where tom attacks, vocal body, and bass impact occur, while preserving useful extension into the low frequencies.

Recommended Tuning: A Clear Basis for Enclosure Design

To facilitate integration, a recommended enclosure is provided: 60 liters with a 60 Hz tuning. This guideline offers a solid starting point for designing a bass-reflex enclosure oriented toward efficiency, to be adjusted according to goals (throw, low-frequency extension, enclosure size) and the planned crossover.
