The RCF CD400 is a professional-grade compression driver built for system integrators, OEM speaker builders, and live sound technicians sourcing reliable HF transducers for horn-loaded enclosures. The 1.75-inch polyester diaphragm paired with a 1.0-inch exit throat makes it a direct fit for a wide range of industry-standard horn flares used in installed audio, touring line arrays, and point-source cabinets. The 2-slot optimized phase plug geometry and vented suspension system work together to maintain smooth response at the top of the frequency band, where lesser drivers compress or break up under sustained program levels.

At 50W RMS continuous and 100W program power handling, the CD400 holds up in demanding live applications without thermal compression becoming a liability. The Kapton voice coil former and edgewound aluminum winding are designed to shed heat efficiently, keeping performance stable during extended high-SPL sets. For integrators building or refurbishing speaker systems, this driver offers a technically complete solution: ceramic magnet structure, PP composite phase plug, and CE compliance confirm it meets the build standards expected in professional installations and touring rigs alike.
