  • Neodymium Magnet Assembly Cuts Weight Versus Comparable Ceramic Midrange Drivers
  • Aluminum Sealed Basket Eliminates Rear Chamber Requirement For Simpler Cabinet Builds
  • Inside/Outside Dual-Layer Voice Coil Maximizes Conductor In Gap For High Motor Strength
  • Calibrated Back Volume Optimizes Time-Domain Transient Reproduction In Horn-Loaded Use
  • Vented Fin Basket Design Improves Heat Dissipation Under Sustained Program Levels
  • Curved Cone With Polycotton Surround Supports Predictable Crossover Integration
  • CE Compliant For Professional Installed And Portable Sound Applications

Cabinet builders, OEM integrators, and touring sound engineers specifying custom enclosures turn to these RCF midrange drivers when output-per-size ratio is the primary constraint. The neodymium magnet assembly cuts total driver weight to less than half that of a comparable ceramic unit, a meaningful advantage when weight budgets are tight across a multi-way touring cabinet or a permanently installed line array column. The sealed aluminum basket eliminates the need for a rear sealing chamber, directly simplifying cabinet routing and woodworking while opening up airflow paths that keep the voice coil cooler under sustained program levels.

Both drivers share a 3-inch aluminum voice coil wound in an inside/outside configuration across two layers, a geometry that maximizes the conductor in the gap and contributes to the high BL factor that defines the motor's authority over the cone at midrange frequencies. The calibrated back volume is engineered to optimize time-domain transient reproduction, which separates these drivers from generic OEM midrange units where phase coherence in horn-loaded applications is an afterthought. The curved cone and polycotton surround work together to maintain controlled dispersion through the driver's operating band, making crossover integration predictable for designers working with DSP-based active systems. CE compliance confirms the drivers meet European safety standards for professional installed and portable sound applications.
