Description du produit RCF MB12N251

Haut-parleur Néodyme 12" mid-bass, 2,5" VC, 300 W rms / 600 W max


The MB12N251 is a 12”  neodymium mid-bass driver with an excellent linearity, good efficiency and high power handling capabilities. The 2,5” aluminium voice coil combined with a high strength fibreglass former allows high efficiency and good frequency response extension. Aluminium basket and magnetic assembly design provide an excellent heat dissipation and very low power compression.

The Triple-roll shape combined to spider design offer very low distortion and extended low frequency reproduction.

Applications

    * • The MB12N251 finds its application in 2-way bass reflex system, typically combined with 1" and 1,4" throat compression drivers. Ideal for light weight portable applications.
