The RCF CDK455 is a professional-grade compression driver built for loudspeaker designers and OEM cabinet builders who need a high-sensitivity, reliable transducer for two-way point source enclosures. Its 1" exit throat and low recommended crossover point make it a practical choice for compact full-range cabinets used in installed sound, touring line arrays, and stage monitor designs where tight packaging is a priority.
The CDK455 pairs a 1.75" voice coil wound with edgewound aluminum on a Kapton former with a Polyimide dome and flat suspension. New bonding technology and reinforced dome ribs extend long-term durability under continuous professional use. Ceramic magnets and a 2-slot optimized geometry phase plug work together to maintain sensitivity and control distortion across the operating bandwidth, making this driver a dependable foundation for consistent cabinet-to-cabinet performance in production environments.
For integrators and cabinet manufacturers evaluating compression drivers in this class, the CDK455 delivers a measurable 109 dB sensitivity with 140 watts of program power handling, a flux density of 1.5 T, and CE compliance. Its compact footprint and standard 4-hole mounting pattern simplify integration into new designs or direct replacement applications without modification to the baffle.
