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.
