Active Subwoofer for Live Sound Systems
RCF SUB 18-AX is an 18-inch active subwoofer designed for portable use and installations in small to medium-sized venues. It delivers powerful low-frequency performance and flexible system control with built-in crossover presets, parametric EQ, and advanced signal processing. The subwoofer also pairs well with speakers featuring 10”, 12”, or 15” drivers.
Integrated DSP and User Interface
The SUB 18-AX features a digital control section offering extensive configuration options. A 2.4-inch color touchscreen and rotary encoder provide intuitive navigation. The internal DSP engine allows detailed control over crossover settings, delay, EQ, and system configurations. Up to eight user profiles can be saved and recalled from the interface.
Timing and System Integration
With factory-preset crossovers tailored for RCF speakers, system integration is both fast and efficient. Precise time alignment between top and sub improves phase response and enhances bass definition. A cardioid mode is available for directional bass control, ideal for live applications.
Remote Control via LiveRemote App
The SUB 18-AX is compatible with RCF’s LiveRemote app, available for both Android and iOS. The app allows wireless control over EQ, crossover settings, delay, and other system parameters. Multiple subwoofers can be linked and configured for stereo or 2.2 setups directly through the app.
