SUB 18-AX PROFESSIONAL ACTIVE 18" SUBWOOFER - RCF

The RCF SUB 18-AX is a portable, high-power active 18" subwoofer built for live sound applications where strong low-end, clarity, and headroom matter. Powered by a 2200 Watt Class-D amplifier and an 18” woofer in a bass reflex housing, it delivers up to 135 dB MAX SPL with controlled performance thanks to Bass Motion Control excursion management. Designed for small to mid-sized venues and portable setups, the SUB 18-AX also acts as the system’s control hub. Its onboard processing includes a digital crossover with recallable presets, plus dual crossovers, 8-band EQs, routing, delays, and cardioid configurations—making it an ideal complement for 10", 12” or 15" woofer-size loudspeakers. Control is straightforward from the color touch panel, and remote adjustments are available via Bluetooth using the LiveRemote App. For connectivity, it offers dual XLR/TRS combo inputs with link and dual XLR crossover outputs for clean integration with a wide range of rigs. The multi-ply hardwood cabinet is polyurea-coated for durability, and power is handled via a sealed Powercon True1 Top AC connector.
