  • PKX Polymer Dome Provides Rigidity And Accuracy Under Sustained Power
  • Kapton Former With Edgewound Aluminum Voice Coil Reduces Moving Mass
  • High-Flux Neodymium Motor System Minimizes Driver Weight In Enclosure Builds
  • Copper Inductance Ring Extends High-Frequency Response With Lower Distortion
  • 3-Slot PP Composite Phase Plug Optimizes Acoustic Loading At The Exit Throat
  • Four-Point Threaded Mounting Pattern Simplifies Horn Alignment And Fitment
  • CE Compliant Construction Meets Professional Installation Standards

The RCF NDX595 is engineered for cabinet designers, OEM integrators, and loudspeaker system engineers who require a compact, high-output compression driver without sacrificing reliability or low-distortion performance. Its ultra-compact footprint and low recommended crossover point make it equally viable in small two-way enclosures and full three-way systems used in touring, installed sound, and professional monitor builds.

The 1.75-inch PKX dome offers a meaningful advantage over standard polyester or titanium diaphragms. PKX, a modified polyether ether ketone compound reinforced with structural ribs, provides a rigidity-to-mass ratio that supports accurate high-frequency reproduction under sustained high-power conditions. Paired with a Kapton former, edgewound aluminum voice coil, and a neodymium magnet system rated at 2.1 Tesla flux density, the driver maintains controlled performance across its full operating bandwidth without the weight penalty associated with ferrite motor systems.

A copper inductance ring reduces upper-frequency inductance rise, extending usable response and lowering distortion in the critical presence region. The 3-slot PP composite phase plug optimizes acoustic loading at the 1-inch exit throat, and the four-point 6mm threaded mounting pattern simplifies alignment and fitment into standard horn assemblies. For engineers specifying transducers for fixed-install or production sound enclosures, the NDX595 offers a reliable, measurable, and repeatable platform.
