Overview
The B&C 8FG51-8 is an 8" woofer speaker designed to deliver high-quality sound in professional audio applications. With a continuous program power capacity of 500 W and a 51 mm (2 in) copper voice coil, this speaker offers a powerful and clear audio experience. Its frequency response spans from 50 Hz to 4000 Hz, ensuring accurate sound reproduction across various frequencies.
The speaker is equipped with a shorting copper cap for extended high-frequency (HF) response and a ventilated voice coil gap, reducing power compression for consistent performance over time. With a sensitivity of 93 dB, the B&C 8FG51-8 efficiently converts input power into sound output. Its resonance frequency is 49 Hz, and it's optimized with parameters like a recommended enclosure size of 17.0 dm3 (0.6 ft3) and a tuning frequency of 52 Hz for effective sound reproduction.
Engineered with durable materials and advanced design, the B&C 8FG51-8 is a reliable choice for professional audio setups that demand clarity, power, and reliability.
