B&C 18DS115 – 18″ High-Power Professional Subwoofer

The B&C 18DS115 is a high-performance 18-inch subwoofer engineered for professional audio applications that demand deep bass, high power handling, and reliability. Manufactured in Italy with advanced materials and precision engineering, this driver delivers powerful, clear low-frequency output for touring, installation, and live sound reinforcement systems.

Powerful, Efficient Low-Frequency Reproduction

The 18DS115’s 460 mm (18 inch) diameter allows it to move large volumes of air, producing authoritative bass with excellent impact. Its large cone excursion capability provides deep lows while maintaining control and accuracy, essential for professional audio systems.

The driver features a robust 116 mm (4.5 inch) voice coil designed to handle intense mechanical and thermal stress, enabling it to operate consistently during high-output performances without sacrificing sound quality.

High Power Handling and Thermal Efficiency

Rated at 1700 W nominal power handling and 3400 W continuous program power, the 18DS115 is built to endure the demands of high-output sound reinforcement.

Its advanced motor structure and vented voice coil gap optimize heat dissipation, minimizing power compression and allowing prolonged use at maximum performance levels. This thermal management keeps bass response clean and distortion-free, even during extended gigs or installations.

Smooth Frequency Response and High Sensitivity

With a frequency range of 30 Hz to 500 Hz, the 18DS115 covers the fundamental bass spectrum needed across music and speech applications. This range ensures punchy, deep lows with clarity and minimal distortion.

The driver’s nominal impedance is 8 ohms, with a minimum of 7 ohms, allowing straightforward integration into most amplifier configurations.

At 98 dB sensitivity (1W/1m), the 18DS115 efficiently converts amplifier power into powerful sound output, making it well suited for large venues, festivals, and fixed installations requiring dependable bass coverage.

Rugged Construction for Professional Durability

Designed to withstand the rigors of touring and long-term installation, the 18DS115 uses premium materials and features like a double silicone spider for mechanical stability and optimized lead wires to reduce mechanical noise.

The cone is treated with B&C’s TWP (Total Waterproof) coating, providing moisture resistance for outdoor and humid environments, ensuring reliable operation regardless of conditions.

Versatile Applications and Integration

The 18DS115 is ideal for a wide range of professional uses:

• Subwoofer Cabinets: Perfect for vented or bandpass designs delivering powerful bass response.

• Line Arrays: Suitable for large-scale sound reinforcement systems requiring deep low-frequency extension.

• Touring Systems: Robust and reliable for sustained high-output performance.

• Fixed Installations: Excellent for clubs, theaters, houses of worship, and other venues needing consistent bass impact.

Its combination of power, clarity, and durability makes it a top choice for audio engineers and system designers.
