B&C Speakers 10HPL64 16 Ohms

A B&C 10-Inch Designed for the Bass/Midrange Channel of Modern Speakers

The B&C 10HPL64 is a 10-inch loudspeaker designed to effectively cover the area where the energy and intelligibility of a system are played out: the upper bass and low-midrange. Its compact size facilitates integration into enclosures with low internal volume, while the use of a neodymium magnet meets current portability needs without sacrificing the primary goal of a sound reinforcement transducer: handling power and remaining clear at high levels.

With a sensitivity of 98.5 dB (1 W / 1 m) and a performance-oriented design, it naturally fits into speaker projects seeking good output levels with controlled amplification, especially in multi-way systems or as low-midrange reinforcement.

Who Is It For and What Are Its Uses?

This speaker is intended for integrators, technicians, speaker manufacturers, as well as musicians and skilled DIYers designing or refurbishing sound reinforcement speakers. Thanks to its useful frequency range from 60 Hz to 4 kHz, the 10HPL64 is particularly suited for roles as a bass/midrange driver in a 2-way top (with appropriate crossover) or as a low-midrange driver in a 3-way configuration.

Its 16-ohm impedance is advantageous for parallel/series wiring in multi-driver enclosures, optimizing the final impedance seen by the amplifier. It is also a relevant choice when balancing a speaker fleet or respecting impedance constraints in an installation.

Design, Mechanical Elements, and Load Behavior

The 10HPL64 is based on a durability and control-oriented architecture: dual-roll suspension, exponential cone, and single spider. The goal is to achieve a fast and stable response in the low-midrange area while maintaining controlled excursion.

64 mm Voice Coil: Stability and Endurance

The 2.5-inch (64 mm) voice coil, wound with aluminum wire, aims for a good balance between moving mass and heat dissipation. Combined with a power-oriented design, it contributes to the speaker's ability to handle sustained levels and maintain clean dynamics on transients (kick, toms, bass, low vocals, etc.).

Recommended Enclosure: Clear Basis for Effective Tuning

To guide enclosure integration, a recommended load is provided: 26 liters with a tuning at 67 Hz. This guideline helps achieve coherent behavior in the lower spectrum, leveraging a reasonable internal volume. The provided parameters (Fs, Qts, Xmax) then allow fine-tuning of the design (type of enclosure, tuning, crossover) according to the objective: compactness, SPL level, or tonal balance.
