RCF SUB 15-AX active high-power subwoofer

RCF SUB 15-AX active subwoofer is designed to deliver deep, controlled, and high-impact bass for professional sound reinforcement systems used in live concerts, DJs setups, and small to medium venue applications. It combines a powerful 2200W Class-D amplifier with a precision-engineered 15-inch woofer housed in a bass reflex cabinet to achieve strong low-frequency output with excellent clarity and headroom.

This model integrates an advanced DSP engine with a full-color touchscreen interface and wireless control through the LiveRemote App. These features allow real-time adjustment of crossover points, equalization, delay settings, and system configuration. Factory presets tailored for RCF speaker systems make setup quick and efficient while ensuring optimized performance.

The subwoofer incorporates Bass Motion Control technology, which intelligently manages woofer excursion to maintain deep bass response with reduced distortion and improved linear behavior. Its digital processing section also supports alignment tools, cardioid setups, and recallable configurations for flexible system design.

The enclosure is built using durable multi-layer hardwood and coated with a rugged polyurea finish for maximum resistance during touring use. Ergonomic side handles improve portability, while the steel grille protects internal components without affecting acoustic performance. An M20 pole mount allows integration with satellite speakers, making it suitable for scalable PA systems.
