B&C Speakers 12 HPL 64 4 Ohm

A 12-inch Neodymium Driver Designed for Modern Sound Reinforcement

The B&C 12HPL64 fits within the logic of current PA drivers: achieving a high output level, good power handling, and easy integration into enclosures, all while controlling weight. Its neodymium magnet directly addresses the needs of mobile systems (events, touring, installations requiring a lightweight product), without compromising on serious motor characteristics. With a frequency response rated from 50 to 4000 Hz, it naturally positions itself as an efficient transducer to cover the low and low-midrange, or as the basis of a two-way system with a compression driver and appropriate crossover.

Who Is It For and What Are Its Uses?

This 12-inch speaker targets users who build, repair, or optimize sound reinforcement speakers: contractors, installers, manufacturers, or musicians looking to upgrade a system. Thanks to its high sensitivity, it is particularly suitable for speakers where impact and presence are sought, notably in stage monitors, compact satellite speakers, or front-of-house enclosures of modest size. Its useful range up to 4000 Hz also allows for projects where maintaining clear midrange is desired, provided the crossover and enclosure acoustics are adapted to the intended result.

Design and Performance: What Makes the Difference

Neodymium Motor: Power and Lightness

The choice of neodymium significantly reduces the total mass of the driver while maintaining a motor capable of handling high levels. The 12HPL64 thus weighs only 2.1 kg, which is advantageous for easy-to-transport speakers, flown systems, or any application where every kilogram counts.

Efficiency and Projection

With a declared sensitivity of 100 dB (1W/1m), this model is geared towards efficiency. Practically, this favors a sense of dynamics and projection, and can help achieve a high sound level with reasonable amplification, depending on the load, crossover, and usage context. This is a key point for PA speakers where good clarity and comfortable volume levels are expected.

64 mm Voice Coil and Materials

The 64 mm voice coil diameter combined with a 12.5 mm winding height contributes to power handling and thermal behavior. The aluminum voice coil material supports a responsive assembly, designed for clean response in the bass/midrange area. The whole is consistent with professional use where stability and repeatability of performance are essential.

Enclosure Integration: Dimensions to Check

Before replacement or design, it is important to verify mechanical compatibility: overall diameter 315 mm, mounting diameter 282 mm, total height 144 mm, and basket inner diameter 296 mm. These dimensions facilitate integration but should be compared with your baffle, grille, and any available rear volume.
