RCF EVOX J11 Black 3-Way Portable Active Column PA System
DETAILS
RCF EVOX J11 Black – Ultra-High Power Three-Way Active Column PA System with Advanced DSP.
The RCF EVOX J11 Black is a flagship three-way active column PA system designed for maximum output, clarity, and performance in demanding live sound environments.
Featuring a 1.75” neodymium compression driver with True Resistive Waveguide, twelve 3” neodymium full-range transducers, and a high-power 12” woofer, the EVOX J11 delivers exceptional vocal clarity, detailed midrange, and deep, controlled low frequencies. Powered by a massive 3500W Class-D amplifier and capable of producing up to 132 dB Max SPL, the EVOX J11 is ideal for large venues, DJs, live bands, corporate events, and professional productions where high output and pristine sound quality are essential.
High-Powered Class-D Amplification
The EVOX J11 is driven by RCF’s next-generation 3500W dual-channel Class-D amplifier, delivering up to 2.5x more power than previous architectures. This provides ultra-fast transient response, realistic dynamics, and extremely high sound pressure levels with minimal thermal build-up.
The fanless cooling system uses a solid aluminium heat exchanger for silent operation and long-term reliability. The advanced input stage includes low-distortion circuitry and an intelligent safety limiter to preserve signal quality at any level, while the SMPS power supply ensures high efficiency with reduced overall system weight.
Exceptional Sound with True Resistive Waveguide
At the core of the EVOX J11 is a 1.75” neodymium compression driver coupled with RCF’s True Resistive Waveguide, delivering consistent 120° horizontal and 40° vertical coverage. This ensures even sound dispersion across wide audiences with outstanding intelligibility.
The forward-facing array of twelve 3” neodymium full-range drivers delivers a balanced point-source response with high sensitivity and clarity, while the high-excursion 12” woofer in a bass-reflex enclosure produces deep, controlled bass suitable for high-energy music and live performance.
Designed for Portability and Easy Setup
Despite its exceptional power, the EVOX J11 maintains a sleek, unobtrusive design that blends into any environment. The lightweight composite cabinet with aluminium stand mount allows for fast deployment, making it ideal for mobile and fixed applications alike.
The system includes a padded carry bag for the two-piece column array, ensuring safe transport and quick setup. Optional pole extensions, protective covers, and trolley systems are available for enhanced flexibility, touring, and long-term storage.
Advanced DSP, FiRPHASE & Bass Motion Control
The EVOX J11 features RCF’s real-time DSP platform, incorporating proprietary algorithms for system protection and acoustic optimisation. FiRPHASE processing ensures precise phase alignment, transparent sound, and consistent coverage with minimal latency.
Bass Motion Control (BMC) allows the system to reproduce extremely low frequencies without compromising woofer stability. Unlike traditional high-pass filters, BMC preserves phase and frequency response while protecting the driver from over-excursion, resulting in deeper bass and improved overall sound integrity.
