B&C Speakers 15FW76

A 15-inch (38 cm) driver designed for sound reinforcement: the B&C signature in 15-inch format

The B&C 15FW76 is a 15-inch (38 cm) bass driver designed for sound reinforcement applications where level, reliability, and controlled response are sought. Featuring a ferrite magnet and an endurance-oriented design, it fits within the "workhorse" transducer logic: capable of handling long sessions at high volume while maintaining clear and dynamic bass.

Who is it for and what are the applications?

This model targets integrators, speaker manufacturers, service providers, and DIY enthusiasts looking for an efficient 38 cm driver to build a subwoofer or a low-mid/bass reinforcement speaker. Its recommended enclosure tuning of 80 liters at 50 Hz provides a clear design basis to achieve impactful bass, suitable for contemporary music, powerful stage monitors, or live sound systems where acoustic pressure and mechanical durability are priorities.

Design, features, and key elements

3-inch voice coil and copper wire: thermal stability and control

The 3-inch (76 mm) copper wire voice coil contributes to the 15FW76's ability to withstand heavy demands. This architecture is designed to maintain driver control as levels increase, delivering a coherent response in the bass and low-midrange region, with a power handling rated at 1000 W AES.

Triple roll suspension and 7 mm Xmax: controlled impact and excursion

The triple roll suspension combined with a 7.0 mm Xmax promotes solid and consistent excursion, useful for preserving impact without losing control of movement. The result is firm and fast bass, particularly effective in bass-reflex enclosures optimized for efficiency.

Exponentially shaped waterproof treated cone and double silicone spider: built to endure

The exponentially shaped cone with waterproof treatment on the front helps maintain performance under intensive usage conditions. The double silicone spider enhances mechanical stability, a crucial factor when the driver operates at high levels over time, limiting unwanted behaviors and improving repeatability.

Parameters useful for speaker design

With a resonance frequency (Fs) of 40 Hz and a Qts of 0.21, the 15FW76 is typically comfortable in designs aimed at efficiency and punch. The recommended enclosure volume of 80 liters with a 50 Hz tuning provides a straightforward framework to start a project, optimize alignment, and target a balanced compromise between depth, efficiency, and power handling.
