RCF KX 45-A Description

The RCF KX 45-A redefines what’s possible in a compact touring-grade speaker. Equipped with a high-powered 15" neodymium woofer and a 4" titanium dome compression driver, this 2-way active speaker delivers consistent, high-definition sound across its wide 100° x 70° dispersion. Its rotatable TRW waveguide ensures optimal coverage in both vertical and horizontal configurations, making it a powerful tool for FOH, monitor, or distributed PA applications. Powered by a 3200W two-channel Class-D amplifier, the KX 45-A leverages RCF’s advanced DSP platform with FiRPHASE for time-aligned phase coherence and Bass Motion Control (BMC) for deep, controlled low-end response. RDNet integration enables full remote control over DSP parameters, monitoring of internal sensors, and real-time diagnostics—ideal for complex installations or touring systems. Constructed from water-resistant Baltic birch plywood and finished with a rugged polyurea coating, the cabinet is built to withstand demanding environments. Internal reinforcements, die-cast aluminum handles, and a fanless aluminum heat sink ensure durability and ease of transport. Whether ground-stacked, flown, or pole-mounted, the KX 45-A provides uncompromising performance with maximum flexibility.
