The RCF ND650 is engineered for sound reinforcement professionals who demand accurate, high-output high-frequency reproduction across touring, installed sound, and live production environments. Built around a 2.5-inch pure titanium diaphragm and a 1.4-inch exit throat, the ND650 delivers the kind of extended response and low distortion that system integrators and speaker cabinet builders require when specifying drivers for horn-loaded enclosures.
The driver's construction reflects a rigorous approach to thermal and acoustic performance. A high-temperature Kapton former and edgewound aluminum voice coil winding handle sustained program levels without compression artifacts. The vented, flat polyester suspension minimizes distortion under dynamic loads, while the copper demodulation ring reduces inductance-related coloration for cleaner transient response across the full operating range. A three-slot aluminum phase plug optimizes wavefront geometry at the exit throat.
Compared to generic OEM compression drivers in this class, the ND650's neodymium magnet assembly delivers a high flux density in a compact, low-profile form factor. The CE-compliant design mounts via four threaded holes, making it a practical choice for custom cabinet builds, speaker repair on RCF cabinets, and integration into touring systems where verified performance data is essential for crossover design and system alignment.
