B&C Speakers 12 HPL 76

Key Information About the B&C 12HPL76 12-inch (31 cm) Midbass Speaker

• High sensitivity with 99 dB (1 W/1 m) for effective sound reinforcement projection.
• High power handling : 700 W AES at 8 ohms, designed for demanding systems.
• Lightweight and efficient format thanks to the neodymium magnet (3.2 kg), ideal for portable speakers.
• Versatile useful frequency range : 50 Hz to 3.5 kHz to cover low and low-mid frequencies in a 2-way configuration.

A B&C Reference Focused on Sound Reinforcement: Power, Sensitivity, and Compactness

The B&C 12HPL76 is a midbass speaker in a 12-inch format, designed with a "pro audio" mindset: high sensitivity, excellent mechanical durability, and a modern neodymium motor to reduce weight without sacrificing dynamics. Its design naturally positions it in sound reinforcement solutions where a responsive transducer is needed, capable of handling power and linear enough to provide a solid low-end foundation while remaining clean in the midrange.

Who Is It For and What Are Its Uses?

This model is aimed at integrators, contractors, speaker manufacturers, and DIY enthusiasts who want to build or refurbish a sound reinforcement speaker based on a 12-inch driver. With its frequency response from 50 Hz to 3.5 kHz and high sensitivity, it fits particularly well in a 2-way speaker (with a tweeter and appropriate crossover) or as a low-mid reinforcement speaker, depending on the chosen architecture. Its neodymium magnet and light weight also make it a relevant choice for portable systems, where every kilogram counts.

Design and Key Features: Efficiency, Control, and Reliability

3-inch (76 mm) Voice Coil: Thermal Handling and Control

The 12HPL76 is equipped with a 3-inch (76 mm) voice coil with aluminum wire. This choice aims to combine robustness, heat dissipation, and fast response to maintain definition in the low-midrange while supporting high levels over time.

Double Roll Suspension and "Pro" Architecture

The double roll suspension, combined with a single spider, contributes to stable mechanical durability and controlled behavior during large excursions. With an Xmax of 4.0 mm, the speaker remains comfortable in the bass register for a 12-inch sound reinforcement driver, while retaining the necessary attack on transients (kick, bass, toms, etc.).

Exponential Cone: Projection and Articulation

The exponential cone is designed to enhance projection and articulation in the low-midrange area, useful for the clarity of vocals, guitar, keyboard, or overall front-of-house mix. This design supports the goal of a "punchy" and efficient 12-inch driver capable of filling a room without overdriving the amplifier power.

Recommended Enclosure: A Clear Basis for Speaker Design

For enclosure design, a simple recommendation is provided: 40 liters with a tuning at 70 Hz. This is valuable data for quickly sizing a compact bass-reflex speaker, consistent with the "sensitivity/portability" spirit of this transducer.
