B&C Speakers 15SW100

A B&C Transducer Built for the Modern Subwoofer: Power, Control, and Reliability

The B&C 15SW100 is part of the professional subwoofer speaker range designed to withstand sustained operation while maintaining clean and controlled bass. Its architecture emphasizes thermal management, mechanical stability, and the ability to produce high sound pressure levels-requirements that have become central in today's bass-reflex sound reinforcement enclosures.

With its neodymium magnet and "useful performance" oriented design, this 15-inch (38 cm) driver targets both fixed installations and mobile systems where weight and overall efficiency are as important as the final output level.

Intended Uses and Users

This 15-inch subwoofer speaker is aimed at integrators, loudspeaker manufacturers, sound contractors, and demanding DIY enthusiasts looking for a driver capable of delivering solid, clear, and impactful bass. It is particularly suitable for enclosures dedicated to amplified music (electronic, hip-hop, rock, live), as well as sound systems where excellent long-term power handling is expected.

Thanks to its recommended enclosure volume of 120 liters with a tuning at 35Hz, it naturally fits into a bass-reflex cabinet optimized for deep extension while retaining dynamics and control. It can also be integrated into subwoofer stacks where repeatability and reliability of performance are essential.

Design and Key Features: What Makes the Difference in the Field

Thermal Endurance and Power Control

The 4-inch (100 mm) copper wire voice coil is a central element for handling high levels, limiting power compression, and maintaining consistent bass when the system is pushed hard. This approach aims for a more stable response during long performances, where consistent efficiency is as important as nominal power.

Excursion, Suspension, and Mechanical Control

With an Xmax of 12.5 mm, the 15SW100 is designed to move air and withstand the heavy demands typical of sub frequencies. The triple roll suspension promotes movement stability, while the double siliconed spider enhances centering and mechanical strength. The result is safer behavior at high levels, with bass that remains tight and usable.

Protection and Heavy-Duty Use

The radial cone benefits from waterproof treatment front and back, a valuable asset for touring conditions, humidity variations, or installations where robustness is paramount. This design contributes to the transducer's longevity and the consistency of its performance over time.
