B&C 18TBX100 – 18″ High-Output Professional Subwoofer

The 18TBX100 from B&C Speakers is a top-tier 18-inch subwoofer engineered for high-power professional audio applications. With robust thermal management, low distortion design, and high efficiency, the 18TBX100 delivers deep, clean bass in touring systems, fixed installations, and portable PA enclosures.

High Output with Deep Bass Extension

With a nominal diameter of 460 mm (18 in), the 18TBX100 moves significant air volume, making it ideal for high-impact bass performance. Its frequency range of 35 Hz to 1,000 Hz ensures precise low-frequency extension, delivering punchy lows without midrange muddiness.

The driver suits both vented and bandpass cabinet designs and provides tight bass that enhances clarity in full-range sound systems.

Impressive Power Handling and Low Distortion

The 18TBX100 is rated for 1,200 W nominal and 2,400 W continuous program power, offering ample headroom for demanding professional setups. Advanced cooling and a ventilated voice coil gap minimize heat buildup, helping the driver maintain stable output over extended use.

An aluminium demodulation ring reduces distortion by linearizing the magnetic flux during excursion, preserving clarity even under high load.

High Sensitivity and Effortless Efficiency

At 94 dB sensitivity, the 18TBX100 delivers significant acoustic output from moderate amplifier power—ensuring clean, powerful low-end without taxing the system. This efficiency suits large-format and high-performance systems where reliability and headroom matter.

Stable Impedance and Seamless Integration

Operating at a nominal impedance of 8 Ω (with a minimum of 6.2 Ω under dynamic conditions), the 18TBX100 integrates easily into amplifier setups and passive crossover networks. Its consistent impedance behavior makes system matching straightforward for technicians and designers.

Precision Build and Durable Construction

The subwoofer features a 100 mm (4 in) copper voice coil wound on a glass-fibre former, engineered for thermal durability and mechanical stability. A double silicone spider with optimized compliance supports high excursion while keeping distortion low.

Treatment on both sides of the cone provides water resistance, supporting reliable performance even in humid or outdoor environments.

Applications and Utility

• Touring Systems: Delivers deep, tight bass for high-SPL live events

• Fixed Installations: Ideal for venues, clubs, and theaters where headroom and response consistency are essential

• Portable PA Enclosures: Efficient power handling in vented or bandpass top boxes

• OEM Speaker Systems: Reliable performance in distributed subwoofer designs or large-format builds

The 18TBX100’s mix of power, sensitivity, and build quality makes it a go-to subwoofer for professionals requiring bass precision under pressure.
