The RCF J11 is an active, three-way portable column system designed for maximum clarity and power in a compact format. A 1.75" compression driver on a 120° x 40° True Resistive Waveguide ensures wide, consistent coverage, while 12 x 3" full-range transducers and a high-power 12" woofer in a bass-reflex enclosure deliver articulate mids and deep, controlled lows. Driven by a 3500W onboard dual-channel Class-D amplifier, the J11 delivers an impressive 132 dB Max SPL output. Part of the EVOX J Series, it incorporates RCF's touring-grade technology into a sleek, unobtrusive package that delivers crystal-clear vocals, natural musical response, and a straightforward setup for bands, DJs, and live performers.
