EVOX J11 is an active three-way portable column system designed for maximum clarity and power in a compact format. Tour-grade RCF technology in a sleek, unobtrusive package — crystal-clear vocals, natural musical response, and effortless deployment for bands, DJs, and live performers.
3500 W
Up to 2.5× More Power
The new generation Class-D dual-channel amplifier delivers up to 2.5× more power than the previous architecture — extremely high SPL with ultra-fast attack, realistic transient response, and minimal thermal buildup. Fanless design with solid aluminium heat exchanger. Switch-mode power supply for high efficiency and minimal weight.
True 3-Way Design
Three Transducer Types. One Coherent System.
A 1.75" neodymium compression driver (Kapton dome) coupled with a True Resistive Waveguide (TRW) delivers resonance-free load and constant 120° × 40° coverage.
12 × 3" full-range neodymium transducers in a forward-radiating array combine with the centred waveguide for a balanced point-source response across the full frequency range.
A high-power 12" RCF woofer in a bass-reflex enclosure delivers deep, controlled low frequencies — ideal for bass-heavy music and high-energy performances.
132 dB
Maximum SPL
Driven by 3500W of onboard amplification, EVOX J11 delivers exceptional output levels whilst maintaining clarity and control at any volume.
Fast Flexible Deployment
Quick Setup. Ready to Play.
Available in black or white, EVOX J11 integrates all required connections for fast setup. Despite its power and size, its sleek composite cabinet remains unobtrusive and neutral, blending into any environment.
The included padded carrying bag for the two-piece column array makes moving the system effortless. For increased height, J11 supports a single half-pole, full-column array configuration.
ACE Subwoofer Integration
When extended low-end is required, add an RCF SUB AX series subwoofer. ACE-enabled subs include dedicated EVOX integration presets — perfect tuning at the touch of a button via RCF's Advanced Crossover Engine.
Bass Motion Control®
BMC creates a complete map of the woofer's dynamic behaviour to generate a custom algorithm limiting overexcursion — protecting the driver while enabling full freedom in signal reproduction, unlike traditional high-pass filters.
FiRPHASE DSP
RCF's proprietary FiRPHASE processing delivers linear phase response across the crossover region, preserving transient accuracy and maintaining coherent wavefronts for natural, detailed sound reproduction.
Digital Signal Processing
Engineered to Perform
Real-Time DSP Platform
The EVOX J DSP platform delivers unparalleled processing density and scalability, incorporating all RCF proprietary algorithms for protection and tuning — advanced limiting, Bass Motion Control, FiRPHASE, and ACE crossover presets.
Advanced Amplifier Design
New low-distortion input stage with an advanced safety limiter that preserves the input signal's character at any level. Designed to EN 62368-1 standard. Mechanically coupled amplifier is securely braced within the composite cabinet for long-term reliability.
