RCF Evox J8 Active Two Way Portable Array

    Get Stunning Sound Quality And Convenient Portability With The RCF Evox J8 Active Two Way Portable Array

    The incredibly powerful EVOX series alters the landscape of portable PA once again. The system features a line source satellite module with eight 2” full-range drivers paired with a high-powered 12” woofer in a bass reflex enclosure. All powered by on-board 1400‑watt Class-D amplification. The EVOX J Series maintains a similar footprint to the original EVOX systems, now in a portable composite enclosure. The system offers stunning sound performance with crystal clear vocal reproduction and unparalleled musical response. This makes the RCF EVOX the smart choice for live entertainment, DJs, parties, club music and corporate events.

    FIRPHASE

    RCF speakers are designed by using FiRPHASE, a proprietary and advanced FIR filtering technology, conceived for delivering transparent sound, absolute clarity and perfect stereo images to the listener. The FiRPHASE algorithm optimizes dynamics, amplitude and phase patterns, ensuring at the same time minimum system latency.

    PHASE MATTERS

    The design of the FIR filter for this specific purpose should start from an accurate measurement of the loudspeaker phase. The FiRPHASE algorithm uses this measurement and adapts the loudspeaker’s phase without touching the amplitude equalization. The heart of the advanced technique used by FiRPHASE is a recursive method (Least Squared method) combined with a proprietary algorithm that calculates the best FIR filter coefficients set in according to amplitude and phase constraints. The algorithm corrects phase and amplitude (when necessary) by taking into account the weak points of the transducers and the resonances or cancellations due to the cabinet of the loudspeaker. Despite the design perfection of our transducers and cabinets, we realize that the phase corrections are the “missing point” for the perfection. This technique allows a deep control of phase at mid-low frequencies with relatively small filters, reaching a higher resolution than that one as theory suggests.
