B&C 15TBX100 – 15″ High-Power Subwoofer Driver

The 15TBX100 from B&C Speakers is a powerful 15-inch subwoofer driver engineered for pro audio systems that demand deep, clean bass and high reliability. Designed for both touring and installation use, it combines high power handling, solid sensitivity, and rugged mechanical design. Whether you’re building high-output sub cabinets or bass modules in full-range enclosures, the 15TBX100 delivers authoritative low end with control and efficiency.

Deep Bass Extension & Wide Usable Range

The 15TBX100 features a nominal diameter of 380 mm (15 inches), giving it the cone area required to push significant bass output. Its frequency range of 35 Hz to 1500 Hz makes it versatile for handling sub-bass fundamentals, bass-mid content, and transitioning smoothly into midrange when used in multi-way systems.

It delivers tight, punchy bass down low without losing clarity, and its upper limit lets it integrate cleanly with mid or high drivers without smearing or harshness.

High Power Handling & Thermal Capacity

The 15TBX100 maintains nominal power handling of 1000 W and continuous program power of 2000 W, providing substantial headroom for dynamic audio content and high SPL requirements.

Its 100 mm (4-inch) copper voice coil is built to endure thermal stress, supported by a ventilated voice coil gap and robust motor structure. These design features help reduce power compression and maintain performance consistency even in prolonged use or under heavy demand.

Efficiency & Sensitivity

With a sensitivity of 96 dB (1W/1m), the 15TBX100 converts amplifier power into loud, usable bass with less strain. This level of sensitivity is strong for a 15-inch driver, allowing for efficient volume and dynamic response without needing overpowered amplification.

The efficiency ensures that the 15TBX100 performs well in both subwoofer applications and bass-module roles, giving you punch and authority with reasonable amp demands.

Electrical Behavior & System Matching

The driver runs at a nominal impedance of 8 Ω, with a minimum impedance of approximately 6.2 Ω, providing stable electrical loading for typical amplifiers and crossover networks.

That predictable behavior simplifies design integration, ensures amplifier compatibility, and helps avoid mismatch issues in complex systems or when using multiple drivers.

Rugged Mechanical Design

Built for durability, the 15TBX100 features a robust suspension with double silicone spider, a demodulating ring to reduce distortion, and a treated cone for improved resistance to environmental stress.

Its mechanical design supports high excursion (about ±9 mm), ensuring that the driver can move properly without distortion even under demanding conditions. The materials and build quality are chosen to endure high output, transport, and prolonged usage without rapid deterioration.

Ideal Applications

The 15TBX100 is particularly effective in:

• Vented subwoofer cabinets needing deep bass and high SPL

• Bass-module use in full-range top boxes or line array setups

• Touring PA systems where strength, reliability and clean low-end are essential

• Fixed installs like clubs, arenas, or venues needing dependable bass modules

• OEM loudspeaker builds that demand consistency, durability, and strong output

Its combination of extended reach, power handling and efficient output make it a go-to for professional designs requiring serious low-frequency muscle.

Performance Summary

The 15TBX100 gives deep, clean bass with real authority. Its design handles power well, with strong thermal characteristics and minimal compression under load. The high sensitivity ensures usable SPL with lower amplifier strain, while the voice coil and mechanical architecture enable strong excursion without distortion.

In large sub cabinets or bass-modules where bass fidelity, output, and reliability are non-negotiable, the 15TBX100 delivers solid, repeatable performance.

Conclusion

If you need a 15-inch subwoofer driver that balances deep, powerful bass with efficiency and rugged dependability, the 15TBX100 is a strong choice. It’s engineered for serious audio setups—touring rigs, fixed installs, or high-output top boxes. For system designers and engineers wanting low-end strength without sacrificing clarity and reliability—15TBX100 delivers exactly what’s required.
