Koax. reproduktor 15"/1", 300/50W, 101/110dB, 40-20000Hz, X-max 5,5mm, vyzař.úhel 60°, hmotnost 7,3kg

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