RCKX45A

KX 45-A

RCF

Designed specifically for professionals deploying top-tier sound reinforcement at live concerts, performing arts centers, sports venues, and premium installations, the RCF KX 45-A is a 3200W active 2-way point-source speaker that's tuned for absolute clarity and deep, powerful bass. The KX 45-A combines precise directivity, high SPL capability, and advanced system integration. A 3200W amplifier delivers 2000W to the 15" neodymium woofer in a bass-reflex design, while a 1200W amplifier powers the high-frequency neodymium compression driver with a 4" titanium dome, coupled to a 100 x 70 True Resistive Waveguide, rotatable by 90 to ensure flexible coverage options. The integrated amplifier features proprietary DSP processing and remote management via RDNet that enable optimal system performance. The rugged, tour-ready, high-quality Baltic-birch plywood cabinet is easy to carry and installed securely using the dedicated rigging points.At a Glance 137 dB Max SPLRotatable 100 x 70 TRW horn15 neodymium woofer, 3.5 voice coil4 Titanium dome, neodymium compression driver2 channel, 3200W Class-D AmplifierDSP Processing with FiRPHASE and BMCRDNet Networked ManagementpowerCON TRUE1 TOP mains connectorsPreset Selector CLOSE (C) Designed for listening distances less than  13':C1. CLOSE: Reduces high frequencies by -3 dB for a natural, non-aggressive sound.C2. CLOSE HIGH PASS: Same as C1, with a 24 dB/oct high-pass filter at 100 Hz for specific applications.LINEAR (L) Suited for distances of 13 to 36':L1. LINEAR: Offers a perfectly linear response, ideal for outdoor or low-reverb environments.L2. LINEAR HIGH PASS: L1 with a high-pass filter at 100 Hz, ideal for satellite or speech systems.L3. LINEAR LOW LEVEL - PLAYBACK: Linear with a +3 dB bass boost, perfect for low-level playback.L4. LINEAR INDOOR: Adds a -3 dB low-frequency shelf for better balance in reverberant indoor spaces.FAR (F) For distances greater than 36':F1. FAR: Boosts high frequencies by +3 dB to compensate for air absorption, improving clarity.F2. FAR HIGH PASS: Similar to F1 with a 24 dB/oct high-pass filter at 100 Hz.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 FrequencyThe 15 high-power Precision Transducer's cone is equipped with neodymium magnets and a 3.5 voice coil, delivering exceptional power handling and acceleration. By integrating Bass Motion Control (BMC) DSP and a FiRPHASE-optimized crossover, the design extends the low-frequency range and improves midrange efficiency. These technologies align perfectly with the waveguide dispersion, ensuring seamless coverage continuity at the crossover point.High FrequencyPaired with the True Resistive Waveguide (TRW), the 4" pure titanium dome NDT995 compression driver maximizes linearity, precision and long-term reliability. Its motor structure features a high-flux density neodymium magnet assembly, ultralight edge wound aluminum wire, a 4-slot phase plug, and a copper ring design to deliver exceptional power handling, sensitivity, and low distortion across its operating bandwidth. With a very low crossover point at 750 Hz, this allows a better impulse response, fast decay, and superior efficiency.
