The RCF CD650 is engineered for system integrators, speaker builders, and touring production companies who demand consistent, high-efficiency HF reproduction in demanding environments. Its 2.5-inch pure titanium diaphragm provides the thermal stability and stiffness needed to maintain clean output at extended power levels, while the vented polyester suspension minimizes distortion across the operating band. These design choices place the CD650 ahead of drivers using composite or aluminum diaphragms in applications where long-term reliability and sonic clarity are non-negotiable.
The 1.4-inch exit throat mates with standard professional horn formats, making the CD650 a practical replacement or upgrade option for installed loudspeaker systems and custom touring cabinets. The 3-slot optimized geometry phase plug manages wavefront coherence at the exit, reducing comb filtering artifacts that become audible in precision listening environments such as theater, broadcast monitoring, and high-output live sound reinforcement. A copper demodulation ring reduces inductance nonlinearity, extending usable frequency response toward the upper limit of the audible range.
With 109 dB sensitivity, the CD650 pairs efficiently with professional amplifier channels, allowing engineers to reach target SPL levels without overdriving the driver. The high-temperature Kapton voice coil former and ceramic magnet assembly are sized for sustained program power handling, making this driver appropriate for applications that require continuous operation through long events or multi-day installs.
