The CX15N251 is a lightweight coaxial driver with excellent linearity and high efficiency.

The CX15N251 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 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 conical waveguide, provides a clear vocal output and a perfect high frequency extension.
