RCF – KX 45-A

The KX 45-A is a compact, high-performance two-way active system designed for professional users. It combines precise directivity, high acoustic pressure, and advanced system integration. The low-frequency section features a 12" neodymium woofer in a bass-reflex configuration, while the high-frequency section includes a neodymium compression driver with a 1.75" PKX membrane, mounted on a 100° x 70° True Resistive Waveguide that can be rotated by 90°, allowing flexible coverage options. An integrated dual-channel 2000W Class D amplifier with proprietary DSP processing and remote management via RDNet ensures optimal system performance. Its rugged, waterproof multifunctional enclosure with Quick Fit fastening and M10 threads supports a wide range of applications – from ground installations, to stand mounting, to suspension.
