Overview
The B&C 12NW76-8 is a powerful 12" neodymium woofer designed for premium audio applications, boasting a continuous program power capacity of 1000 W and featuring a 76 mm (3 in) copper voice coil for enhanced performance. Its frequency response spans from 40 Hz to 2000 Hz, ensuring versatile and impactful sound reproduction.
This woofer incorporates a neodymium ring magnet assembly and an aluminium demodulating ring, contributing to minimal distortion. The ventilated voice coil gap reduces power compression, while its parameters, including recommended enclosure size of 50.0 dm3 (1.77 ft3) and tuning frequency of 60 Hz, make it optimized for efficient and accurate bass delivery in professional audio setups.
With parameters like resonance frequency of 40 Hz, sensitivity of 98.5 dB, and various quality measures, the B&C 12NW76-8 provides precise and clear sound performance. Its lightweight neodymium construction makes it suitable for applications where weight is a concern.
