The RCF SUB 18-AX is a high-output active 18-inch subwoofer engineered for modern professional sound systems. A 2200 W Class-D amplifier drives a robust 18-inch transducer in a bass reflex enclosure to produce tight, musical low frequencies with headroom to spare, reaching up to 135 dB max SPL. Integrated DSP provides quick, repeatable setup with selectable voicings and a digital crossover for seamless pairing with point source or line array tops. Connectivity is comprehensive: two XLR/jack combo inputs with link outputs, plus two balanced XLR high-pass outs for satellite loudspeakers. RCF’s Bass Motion Control optimises excursion and clarity at high levels, while the durable multiplex hardwood cabinet with rugged polyurea coating is ready for the road. A powerCON True1 inlet ensures a secure, moisture-resistant mains connection, and LiveRemote app support enables convenient control and monitoring. Ideal for live music, rentals, clubs and corporate AV, the SUB 18-AX brings authoritative, controlled bass to any professional system.
