Overview
The B&C 12NDL76 is a 12" neodymium woofer designed for professional audio applications, featuring a remarkable 800 W continuous program power capacity and a 76 mm (3 in) aluminium voice coil. With a frequency response ranging from 50 Hz to 2000 Hz, it achieves an impressive sensitivity of 100 dB, ensuring powerful and precise sound reproduction across various dynamic ranges.
This woofer is equipped with a neodymium magnet that enables a lightweight yet potent motor assembly, contributing to its overall efficiency. The ventilated voice coil gap effectively reduces power compression, maintaining consistent performance over extended use. With a resonance frequency of 50 Hz and parameters like recommended enclosure size of 42.0 dm3 (1.48 ft3) and tuning frequency of 65 Hz, the B&C 12NDL76 is optimized for delivering accurate and impactful mid-range audio.
The combination of its neodymium magnet, aluminium voice coil, and various design features makes the B&C 12NDL76 a reliable and high-performance choice for professional sound reinforcement systems.
