Advanced Electronics

• The high-powered Class-D amplifiers, tailored for each transducer, deploy pristine sound with efficient heat dissipation at the lowest possible distortion, along with low power consumption.
• High-end AD/DA conversion and onboard DSP for the best sound quality. Thanks to the proprietary RDNet networked management and control, every KX speaker provides in-depth remote monitoring through multiple sensors. The system engineer has immediate feedback of transducer status, fan speed, temperature, VU meters, limiters, and much more.

Precision Transducers

Low Frequency

• The 8" high-power cone transducer integrates Bass Motion Control (BMC) DSP and FiRPHASE-optimized crossover to extend the low-frequency range and enhance midrange efficiency, matching the waveguide dispersion for perfect coverage continuity around the crossover point.

High Frequency

• Paired with the True Resistive Waveguide (TRW), the 1.75? compression driver incorporates a newly developed dome crafted from PKX (Modified Polyether Ether Ketone). PKX is a rigid yet lightweight, colorless organic polymer, possibly the best of the thermoplastic resin film for its superior specifications. Designed by the RCF Precision Transducers laboratory, the dome is reinforced with ribs to obtain a slim, but rigid profile. This innovation delivers greater precision and reliability for demanding audio applications.

RDNet Network Control

• RDNet is an advanced platform for integrated monitoring and control of sound system?from small live and installed setups to massive arena systems. Based on a robust networked architecture, RDNet combines system control, line array design, and comprehensive audio measurements into a single powerful software package.
• Engineers and technicians can intuitively manage every device on the network, from individual components to multiple groups. The platform provides full DSP control of compatible devices, with flexible configuration tools for perfectly tuning the system response at maximum speed. Users have real-time access and oversight of all key settings from a centralized interface.

Robust and Durable

The enclosure is made of high-quality Baltic birch plywood, glued with water-resistant adhesive and coated with weatherproof polyurea paint, ensuring excellent waterproofing, UV resistance, corrosion protection, and durability against abrasion, impacts, and mechanical stress. The solid machined aluminum structure efficiently dissipates heat fanlessly, improving enclosure stiffness, while the high-strength structural steel rigging ensures a high safety factor for secure weight management. Die-cast aluminum handles with ergonomic rubber grips enhance usability.

• Durable polyurea paint
• High-strength steel
• Ergonomic handles
• Machined aluminum heat sink

Tour Ready Construction

Attached to a solid machined aluminum structure on the rear panel, the amplifier ensures efficient heat dissipation. The enclosure is internally reinforced and sturdy, equipped with waterproof powerCON TRUE1 TOP mains connectors, guaranteeing durability under any outdoor conditions.

Digital Signal Proficiency

The KX DSP platform is the next-generation audio engine for RCF active speakers and DSP amplifiers. Designed as a real-time DSP engine, it offers unparalleled processing density and scalability, propelling RCF speakers to a new dimension of performance. This groundbreaking DSP engine delivers unmatched processing power for its class.

Bass Motion Control

• KX speakers equipped with Bass Motion Control (BMC) produce the lowest audible frequencies without affecting the woofer stability, with extended linearity and better sound integrity. The BMC method creates a complete map of the dynamic behavior of the woofer, to generate a custom algorithm that limits over-excursions. 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, allowing total freedom of signal reproduction.

New perspective on linearity

• KX speakers are designed using a proprietary and advanced digital FiR technology, conceived to deliver transparent sound, absolute clarity, and perfect imaging to the listener. The special FiRPHASE processing distributes sound to all listeners without phase distortions, ensuring minimum latencies in the system. The algorithm corrects phase and amplitude (if necessary) by taking into account the weak points of the transducers and the resonances or cancellations due to the cabinet of the loudspeaker.
