B&C Speakers 12 NDL 76

A 12-Inch Neodymium Driver in the Spirit of Modern Sound Reinforcement

The B&C 12NDL76 fits within the logic of current sound reinforcement drivers: achieving high output, good definition in the low-midrange, while limiting weight thanks to neodymium. In a 12-inch (31 cm) format, it clearly targets configurations seeking dynamic response, excellent projection, and easy integration into compact enclosures without sacrificing durability.

Who Is It For and What Are Its Uses?

This low/midrange speaker is intended for integrators, manufacturers, and DIY enthusiasts who want to design an efficient 2-way or 3-way sound reinforcement speaker, or to reinforce the "midbass" section of a system. Its useful range up to 2 kHz makes it suitable for crossover with a compression driver (depending on the horn, filtering, and directivity desired) or for a more ambitious multi-way architecture.

The recommended enclosure volume is 42 liters with a tuning at 65 Hz, a practical guideline to start from a coherent base when designing a bass-reflex speaker dedicated to impact and power handling. Whether for a front-of-house speaker, a powerful stage monitor, or a versatile speaker oriented towards "kick/low-midrange," the 12NDL76 emphasizes efficiency and precision.

Design and Key Features

The 12NDL76 is based on an architecture designed for performance and reliability under sustained use. Its 76 mm voice coil (3.0 inches) with aluminum wire is sized to handle heavy demands while maintaining good responsiveness. The choice of a neodymium magnet helps keep weight low, a concrete advantage for portable speakers, modular systems, and installations where handling is frequent.

Response and Load Behavior

With an Fs of 50 Hz and a Qts of 0.2, this model is typically oriented towards alignments that prioritize control and efficiency. The recommended tuning at 65 Hz confirms a "midbass" approach: clean, tight bass and a low-midrange capable of carrying the mix with attack, particularly useful on kick drum, bass, and the low end of amplified instruments.

Mechanical Durability and Musicality

The dual-roll suspension and Xmax of 7.0 mm contribute to a good excursion margin, useful for maintaining presence when levels rise. The exponential cone promotes efficient energy propagation in the low/midrange area, while the single spider ensures centering and stability of the moving assembly within a robust and straightforward design suited to sound reinforcement.
