B&C Speakers 15TBW100

A 15-inch B&C Speaker Oriented Toward "Sub" for Efficient Bass-Reflex Enclosures

The B&C 15TBW100 SUB is a 15-inch speaker designed for low-frequency reproduction in demanding sound reinforcement systems. Its "SUB" designation clearly indicates its purpose: to deliver level, durability, and impact in the low end within dedicated enclosures.

With a recommended enclosure volume of 95 liters and a tuning at 40 Hz, it targets efficient bass-reflex configurations capable of deep extension while maintaining tight bass. This positioning makes it a natural choice for building, maintaining, or optimizing subwoofer enclosures intended for live sound, clubs, fixed installations, or high-end DIY projects.

Who Is This 15TBW100 SUB Suitable For and What Are Its Applications?

This model is primarily aimed at users seeking a professional subwoofer speaker : contractors, integrators, repair shops, enclosure builders, or enthusiasts wanting to assemble a robust sub with recognized components.

Thanks to its 96 dB sensitivity (1 W / 1 m) and high power handling, it fits systems that require sustained high levels without performance drop-off over time. It can be used as a subwoofer, low bass, or low-mid driver depending on the crossover and enclosure design, with a frequency response extending up to 1.5 kHz.

Design and Features: Efficiency, Durability, and Excursion Control

3000 W AES Power: A Solid Foundation for Modern Amplification

With 3000 W AES at 8 ohms, the 15TBW100 SUB is built for current amplifiers and high-impact setups. This power reserve helps limit thermal compression and maintain stable performance when driving the subwoofer for extended periods, especially in amplified music applications.

4-inch (100 mm) Voice Coil and Ferrite Magnet: Efficiency and Robustness

The 4-inch (100 mm) copper wire voice coil directly contributes to the speaker's durability by improving heat dissipation and mechanical strength. The ferrite magnet provides a proven motor structure, valued for its operational stability and consistent behavior under real-world conditions.

Triple Roll Suspension, 12 mm Xmax: Useful Excursion for Bass

For a subwoofer, the ability to move air is critical. With a 12.0 mm Xmax and a triple roll suspension, the 15TBW100 SUB is designed to accommodate significant excursions while maintaining control. The result is clean bass with improved resistance to mechanical stress at high levels.

Waterproof Treated Cone and Double Siliconed Spider: Reliability in Intensive Use

The radial cone receives a waterproof treatment front and back, a valuable feature for speakers likely to operate in variable environments (transport, ambient humidity, stages). The double siliconed spider enhances the stability of the moving assembly, promoting longevity and consistent centering even under heavy use.

Recommended Tuning: 95 Liters at 40 Hz, a Valuable Guide for Enclosure Design

The recommendation of 95 liters with a 40 Hz tuning provides a concrete starting point for designing an efficient bass-reflex enclosure. It helps achieve a deep and usable sub response while keeping the enclosure volume practical for transport and integration.
