The RCF EVOX J11 is a high-performance, three-way active column PA system engineered for DJs, bands, musicians, and live event professionals who need powerful output, exceptional vocal clarity, and consistent sound coverage in a streamlined, portable design. Combining a 12-inch high-power subwoofer, twelve 3-inch neodymium full-range drivers, and a 1.75-inch neodymium compression driver, the EVOX J11 delivers an impressive 132 dB maximum SPL with a frequency response extending from 37 Hz to 20 kHz.
Powered by an integrated 3,500W peak Class-D amplifier and advanced digital signal processing, this professional column speaker system brings together substantial output, controlled bass, natural midrange reproduction, and detailed high frequencies. Its sleek, understated appearance fits comfortably into wedding venues, corporate events, nightclubs, restaurants, houses of worship, and live performance spaces where both sound quality and visual presentation matter.
Powerful Three-Way Sound in a Portable Column System
Unlike conventional two-way portable PA systems, the EVOX J11 uses a true three-way acoustic design to distribute the audio spectrum across dedicated transducers. Twelve 3-inch neodymium drivers reproduce the midrange with clarity and detail, while the 1.75-inch compression driver handles high frequencies through RCF's True Resistive Waveguide. A high-power 12-inch woofer in a bass-reflex enclosure supplies deep, controlled low frequencies for music and live performances.
This carefully integrated configuration delivers a balanced, full-range sound with clear vocals, articulate instruments, and impactful bass, making the EVOX J11 an excellent choice for demanding DJ sets, live bands, speeches, and professional event sound reinforcement.
Wide, Consistent Coverage with RCF FiRPHASE Technology
The EVOX J11 features a True Resistive Waveguide providing 120 horizontal by 40 vertical coverage. This wide horizontal dispersion helps distribute sound across a broad audience area, while advanced RCF FiRPHASE processing optimizes phase response and transient reproduction for precise imaging and natural sound.
Integrated digital signal processing also incorporates RCF's proprietary protection and tuning algorithms. Bass Motion Control (BMC) technology manages woofer excursion while preserving low-frequency extension and sound integrity, helping the system deliver powerful, controlled bass without relying on conventional high-pass filtering that can alter the phase response.
High-Power Class-D Amplification with Integrated DSP
At the heart of the EVOX J11 is a next-generation, two-channel Class-D amplifier rated at 3,500W peak power. Designed for high efficiency and demanding professional use, the amplifier delivers fast transient response and substantial sound pressure levels while minimizing thermal buildup.
Convection cooling eliminates the need for a cooling fan, reducing moving parts and unwanted mechanical noise. An advanced input stage and soft limiter help preserve signal character, while thermal and RMS protection provide additional safeguards during extended operation.
Professional Sound for DJs, Bands & Live EventsThe RCF EVOX J11 is designed to deliver the output and clarity required for a wide range of professional applications. DJs benefit from its powerful low-frequency response and high-output performance, while musicians and live performers can take advantage of clear vocal reproduction and articulate midrange detail. For corporate presentations, weddings, and other speech-focused applications, its wide coverage and dedicated VOICE preset help deliver intelligible, consistent sound.
The integrated processing includes three selectable presetsLINEAR/LIVE, CLUB, and VOICEallowing users to adapt the system's response to different applications without the need for an external processor.
Fast Setup with a Sleek, Road-Ready DesignThe EVOX J11 combines professional output with a streamlined column configuration designed for efficient setup and transportation. Its composite cabinet, steel grille, integrated top handle, and quick-fit column connection create a practical system for mobile entertainers and production professionals who regularly move between venues.
The two-piece column array is supplied with a padded carrying bag for transport and protection. The system supports its standard full-column configuration and an optional half-length pole arrangement for adjusting the column's height. Available in black or white, the EVOX J11 can blend into a wide range of event environments and installation aesthetics.
Flexible Connections & Straightforward OperationThe rear panel provides a balanced/unbalanced combo XLR/-inch jack input, an XLR signal output, volume control, and selectable DSP presets. Power is supplied through professional PowerCON TRUE1 TOP input and output connections, simplifying power distribution in compatible setups.
When additional low-frequency output is required, the EVOX J11 can be integrated with compatible RCF subwoofers. RCF's ACE-enabled SUB AX Series provides dedicated EVOX integration presets that optimize time alignment and phase response for improved system performance.
