B&C 15FW76 – 15″ High‑Efficiency Professional Low‑Frequency Driver

The B&C 15FW76 is a rugged 15-inch low-frequency driver built for professional sound reinforcement systems that require high output, extended bandwidth, and reliable thermal performance. Designed and manufactured in Italy, it balances raw power with refined engineering, making it an ideal choice for everything from touring PA rigs to installed club systems and OEM cabinet designs.

High Output and Extended Low-End Performance

With a nominal diameter of 380 mm (15 inches), the 15FW76 delivers solid low-frequency coverage with plenty of punch. It offers a frequency range of 40 Hz to 2000 Hz, giving it enough bandwidth for both subwoofer and low-mid applications.

Its response is tight and controlled, making it suitable for use in vented enclosures, two-way designs, and front-loaded bass cabinets where clarity and impact are critical. Whether reinforcing kick drums, bass guitars, or full program material, the 15FW76 delivers low-end energy with authority.

Solid Power Handling and Thermal Reliability

Built for high-power applications, the 15FW76 is rated at 500 watts nominal power handling and 1000 watts continuous program power. Its 76 mm (3 inch) copper voice coil is wound on a glass fiber former to ensure thermal stability and mechanical resilience under stress.

The design incorporates a ventilated voice coil gap for improved heat dissipation, reducing the risk of power compression during long periods of operation. A demodulating ring is integrated into the motor assembly to linearize the magnetic field and minimize distortion at high excursion levels.

High Sensitivity for System Efficiency

With a sensitivity of 100 dB (1W/1m), the 15FW76 delivers serious output without requiring massive amplifier power. This makes it well suited for passive systems and power-conscious installations where loudness must be achieved without sacrificing headroom or reliability.

The high sensitivity ensures better gain structure throughout the signal chain and simplifies amplifier matching in multi-driver systems.

Smooth Impedance Curve for Easy Integration

The 15FW76 operates at a nominal impedance of 8 ohms, with a minimum impedance of 6.4 ohms. Its predictable electrical behavior makes it easy to integrate into existing loudspeaker designs, crossover networks, and amplifier setups.

System designers will appreciate the flat impedance response, which simplifies tuning and helps achieve consistent acoustic performance across a variety of enclosures.

Rugged Construction and Proven Materials

Durability is key in professional loudspeaker components, and the 15FW76 is built to take abuse. The cone is made from high-strength treated paper and front-coated for moisture resistance, giving it additional protection in outdoor or humid environments.

A double silicone spider ensures reliable suspension behavior across high excursion ranges, while maintaining linearity and controlling distortion. The overall assembly is designed for long life in portable, touring, or permanent sound systems.

Versatile Applications

The 15FW76 is widely used in:

• Touring bass cabinets and FOH stacks requiring tight low-frequency response

• Two-way top boxes needing a robust woofer with extended upper range

• Fixed installation subwoofers for clubs, theaters, and performance venues

• Stage monitors where mid-bass punch and vocal support are critical

• OEM loudspeaker designs needing consistent, high-output 15-inch performance

Its flexible performance profile makes it suitable for use across many different enclosure formats and tuning styles.
