RCF SUB 18-AX active professional subwoofer

RCF SUB 18-AX active subwoofer is built for high-impact low-frequency reinforcement in demanding live sound environments including concerts, clubs, touring setups, and rental systems. It combines a powerful 2200W Class-D amplifier with a large 18-inch woofer in a bass reflex cabinet, producing deep, controlled bass with high clarity and a maximum output of up to 135 dB SPL.

The subwoofer is equipped with an advanced DSP platform featuring a full-color touchscreen interface and wireless control via the LiveRemote App. This system enables detailed adjustment of crossover points, EQ, delay, routing, and system tuning parameters. Factory-optimized presets allow fast configuration with compatible RCF loudspeakers for efficient and accurate system setup.

Bass Motion Control technology enhances low-frequency performance by intelligently controlling woofer excursion, allowing extended bass response while minimizing distortion and maintaining stability at high output levels. The DSP system also supports alignment functions, cardioid setups, and multi-speaker configurations for flexible professional deployment.

The enclosure is constructed from heavy-duty multi-layer hardwood and finished with a durable polyurea coating designed for touring durability. It includes ergonomic side handles for easier handling, a protective steel grille, and an M20 pole mount for integration with satellite speaker systems.
