The RCF EVOX J11 is an active 12" 3-way 35000W portable line array PA system designed to deliver powerful sound projection for musicians, presenters, and DJs in clubs, parties, and live stage applications.
Class-D amplification pumps 3500W through a 12" high-excursion woofer, twelve 3" full-range drivers, and a 1.75" neodymium compression driver, resulting in a 37 Hz to 20 kHz frequency response with an SPL of 132 dB. The system design produces a 120° horizontal by 40° vertical coverage pattern. Connectivity includes a combo XLR-1/4" input and an XLR output. One column carrying bag, and power cord are included with the EVOX J11.

Fast Transients. Zero Compromise
- The new-generation 3500W Class-D, two-channel amplifier delivers up to 2.5X more power than the previous architecture, delivering extremely high sound pressure levels with ultra-fast attack, realistic transient response, and minimal thermal buildup.
- Highly energy-efficient, the J11 requires no cooling fan. The amplifier is mounted on a solid aluminum heat exchanger at the rear of the unit and has no moving parts. Mechanically coupled to the internal frame, the amplifier is securely braced within the cabinet for long-term reliability.
- The input stage features a new low-distortion design with an advanced safety limiter that preserves the input signal's character at any level. EVOX J11 amplifier is designed in accordance with EN 62368-1 for maximum safety and feature a switch-mode power supply (SMPS) that combines high efficiency with minimal weight.
True 3-Way Design
- Neodymium compression driver (1.75” voice coil, Kapton dome) with a True Resistive Waveguide (TRW) for a resonance-free load and constant, 120x40° coverage.
- The forward radiation of the array of 12 x 3” neodymium drivers, combined with the centered waveguide, delivers a balanced point-source response.
- 12” RCF transducer provides deep, controlled low frequencies, ideal for bass-heavy music and high-energy performances.
SUB AX ACE Presets for EVOX J
When extended, impactful low-end is required, simply add an RCF subwoofer. ACE-enabled models, starting from the SUB AX Series, include dedicated integration presets for EVOX systems, ensuring perfect tuning at the touch of a button. RCF's Advanced Crossover Engine (ACE) precisely adjusts time delay and phase to optimize power and impact of the system.
Quick Setup. Ready to Play
EVOX J11 integrates all required connections for fast setup. Despite its power and size, its sleek design remains unobtrusive and neutral, blending into any environment. The included padded carrying bag for the two-piece column array makes moving the system effortless.
Ready for the Road
Every EVOX system includes a padded column transport bag for essential protection. To complete your setup, add an aluminum pole extension for quick, flexible height adjustments (available in half- and full-height options). For enhanced transport and storage, choose the optional protective subwoofer cover or the trolley-style cover with wheels for easy mobility.
Bass Motion Control
EVOX J speakers equipped with Bass Motion Control (BMC) deliver the lowest audible frequencies without compromising woofer stability, with extended linearity and improved sound integrity. The BMC method creates a complete map of the woofer's dynamic behavior to generate a custom algorithm that limits overexcursions. Traditional high-pass filters protect the woofer from over-excursion but change the phase/frequency response. In contrast, the new BMC algorithm protects the woofer while enabling full freedom in signal reproduction.
FIRPHASE
EVOX J loudspeakers are engineered with proprietary FiRPHASE processing to deliver transparent sound, exceptional clarity, and precise imaging. FiRPHASE optimizes phase response across the listening area, helping provide consistent coverage and a natural transient response while maintaining low system latency. The algorithm refines the transducer transfer function and, where needed, corrects amplitude, reducing the effects of cabinet-related resonances and acoustic cancellations.
