🔊 Smart Control. Massive Bass. Next-Gen Performance.

The RCF SUB 18-AX is a portable 18” high-power active subwoofer featuring advanced DSP control and Bluetooth® connectivity. Delivering up to 135 dB SPL with a powerful 2200W Class-D amplifier, it produces deep, tight, and controlled low-frequency performance with exceptional clarity and headroom.

Designed for modern live sound systems, the SUB 18-AX integrates full system management directly into the subwoofer—making setup faster, cleaner, and more efficient.

A built-in color touch panel also provides direct onboard control when needed.

🚀 Performance That Stands Out

The SUB 18-AX is engineered for maximum output with intelligent control.

Its advanced DSP and Bass Motion Control processing ensure tight, accurate bass even at high volume levels. With onboard system management, it centralizes processing—reducing setup complexity while improving overall system performance.

The 18” transducer delivers powerful, extended low-end that pairs perfectly with 10”, 12”, and 15” top speakers.

🧳 Built for the Road

The rugged all-wood cabinet is finished with a scratch-resistant polyurea coating, built to withstand demanding touring and installation environments.

Its practical design and durable components—including the sealed PowerCON connector—ensure reliable performance in any setup.
