The MB12N251 is 12-inch neodymium mid-bass driver with an excellent linearity, good efficiency and high power handling capabilities. The 2.5-inch 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.
