B&C 12FW76 – 12″ High-Efficiency Mid‑Bass Driver
The 12FW76 from B&C Speakers is a powerful 12-inch professional mid‑bass driver engineered for applications that demand high sensitivity, full-band performance, and reliability. Developed with precision engineering in Italy, the 12FW76 combines long excursion capability and low distortion design to deliver tight, articulate sound.
Clean Mid‑Bass Performance & Wide Bandwidth
Featuring a nominal diameter of 320 mm (12 inches), the 12FW76 delivers substantial mid-bass presence in compact enclosures. Its frequency range of 55 Hz to 3,000 Hz allows it to handle both low-frequency support and mid-range duties with clarity and minimal coloration.
This broad bandwidth makes it ideal for two-way speaker designs, mid‑bass cabinets, and compact stage monitors that demand both power and response accuracy.
High Power Handling & Thermal Efficiency
The driver is rated to handle 500 watts nominal power and delivers 1,000 watts continuous program power, providing ample headroom for demanding audio situations.
A ventilated motor structure and copper aluminum demodulating ring help minimize power compression and distortion under heavy use. This thermal design ensures clean output even during extended performance or high SPL delivery.
High Sensitivity for Efficient Systems
With a sensitivity of 100 dB (1W/1 m), the 12FW76 converts amplifier power into acoustic output efficiently, reducing the overall system power requirements. This high efficiency is especially useful in high-output systems and touring setups where amp headroom and thermal load are critical.
Its performance supports excellent gain before feedback and consistent output in multi-driver audio systems.
Stable Impedance and Easy Integration
Operating at a nominal impedance of 8 ohms, with a minimum impedance of 6.8 ohms, the 12FW76 integrates seamlessly with standard amplifier configurations and passive crossovers.
Its impedance behavior remains predictable across operating conditions, simplifying system design and enabling precise tuning in loudspeaker enclosures.
Precise Mechanical Design and Durability
The 76 mm (3 inch) copper voice coil is wound on a glass fiber former and optimized for thermal stability and linear excursion. The driver’s double half-roll surround and treated cone offer reliable performance in demanding environments.
Its motor assembly includes a demodulation ring to minimize distortion during large excursions, and the cone is moisture-resistant, making it suitable for both indoor and outdoor use.
