Rcf SUB 15-AX W

The SUB 15-AX is a high-powered 15" portable active subwoofer designed for demanding live applications in small and medium-sized venues.

Featuring full signal processing, a color touchscreen and remote control via Bluetooth®, it combines a latest-generation loudspeaker with a Class D amplifier to deliver up to 133 dB SPL with exceptional dynamic reserve.

Powerful subwoofer for live applications

With its 15" driver and high-power Class D amplifier, the SUB 15-AX delivers deep, punchy bass, ideal for live performances, DJ sets or mobile installations. Its sound pressure level of 133 dB SPL guarantees a solid sonic impact, even in medium-sized venues.

Comprehensive system management and advanced DSP

The SUB 15-AX centralizes broadcast system management with comprehensive signal processing: double crossover, 8-band equalizer, matrix, delays and cardioid modes. This allows you to optimize your system's bass response and overall balance, directly from the subwoofer.

Color touchscreen and Bluetooth® control

The color touchscreen provides easy access to all settings: preset selection, delay, filter and cardioid mode settings. Remote control via Bluetooth® allows you to adjust your system without leaving the listening area, for fast, precise set-up, even in live situations.

Ideal complement for 10" and 12" speakers

SUB AX subwoofers are specially designed to complement 10" or 12" loudspeakers. The SUB 15-AX integrates perfectly into a portable system, providing the necessary depth and bass impact, while retaining excellent midrange and treble definition.

Optimized crossover presets for RCF speakers

Integrated, factory-optimized crossover presets for RCF speakers make commissioning your system a breeze. Simply connect your satellites to the SUB AX, select the appropriate preset via the interface, and the linear-phase FiRPHASE crossover ensures an ideal connection between subwoofer and speakers right down to the lowest frequencies.

Robust case and professional connectors

The polyurethane-coated wooden case offers excellent resistance to shocks and transport constraints. The waterproof powerCON TRUE1 TOP connector ensures reliable power supply on stage, while professional audio connectors guarantee easy integration into any modern PA system.
