RCF EVOX-J11 Powered Column Array (Black)

EVOX J11 is an active, three-way portable column system designed for maximum clarity and power in a compact format. A 1.75” compression driver coupled with a 120° × 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, EVOX J11 delivers an impressive 132 dB Max SPL output. Part of the EVOX J Series, it incorporates RCF’s tour-grade technology into a sleek, unobtrusive package that delivers crystal-clear vocals, natural musical response, and effortless deployment for bands, DJs, and live performers.

Elevate Your Sound

EVOX J11 is an active, three-way portable column system designed for maximum clarity and power in a compact format. Neutral and minimal, EVOX J11 stays out of the spotlight and simply delivers. Whether used in corporate spaces or at a party, the sound is clean, with high dynamics, vocal clarity, and a fast, controlled low end for both sitting and standing audience. Free-standing elegance, quick setup, and power at the highest level.

3500 W

Up to 2.5X More Power

The new generation 3500 W 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, 120° X 40° coverage.

The forward radiation of the array of 12x3” 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.

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.

Digital Signal Proficiency

The EVOX J DSP platform is a real-time DSP engine that delivers unparalleled processing density and scalability, propelling RCF speakers to a new level of performance, and incorporates all RCF proprietary algorithms for protection and tuning.

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.

New perspective on linearity

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.
