RCF NX 12-SMA Description

The RCF NX 12-SMA combines compact portability with high-performance sound, making it ideal for stage monitoring and portable PA applications. Its coaxial design features a 12” high-power neodymium woofer paired with a 1.7” kapton dome compression driver for precise point-source sound, resulting in excellent vocal and instrument reproduction with a consistent 60° x 60° dispersion pattern. Driven by a 1400W peak digital amplifier (700W RMS), this speaker delivers up to 129 dB SPL, ensuring clear and powerful sound in demanding live environments. Whether you're performing on stage or setting up a compact front-of-house system, the NX 12-SMA adapts to your setup with selectable EQ modes: “Floor” for wedge use and “Free Field” for standalone PA. The cabinet is constructed from durable Baltic birch plywood and finished with road-ready black paint, designed to withstand the rigors of touring.
