DESCRIPTION DU PRODUIT
Haut-parleur Coaxial - 12" avec 2.5" VC, 1" et moteur ,7" VC, 60x60, 300W+50W.

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 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 80° conical waveguide, provides a clear vocal output and a perfect high frequency extension.
