Reproduktor 12", 300W, 98dB, 45-300Hz, X-max 4,8mm, hmotnost 2,7kg

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.
