RCF CX12N251 - 12" 350W 8 Ohm

The CX12N251 is a lightweight coaxial driver with excellent linearity and high efficiency.

The CX12N251 radiates a coherent single spherical wave front with perfect dispersion control. The design is powered from a large sized single neodymium ring magnet that provides an extremely high flux density and BL factor. The new hyper-vented aluminium basket and magnetic assembly design provide an excellent heat dissipation and lower power compression. Special air-forced ventilations are provided for voice coil, magnet assembly and basket. A 2.5" voice coil combined with a strength fibreglass former and aluminium wire drives the mid-bass cone with high efficiency and a good extension. The 1"7" dome compression driver, loaded to a 60 degree dispersion conical waveguide, provides a clear vocal output and a perfect high frequency extension.

The CX12N251 is the perfect lightweight solution for vocal applications, stage monitoring and compact 2-way reflex enclosures. Ideal in designs where a constant radial directivity pattern is a requirement. Designed for use in compact reflex enclosures and stage monitors.
