  • 2.5-inch , fibreglass former, aluminum voice coil
    600 Watt continuous program power handling
    98 dB Sensitivity
    45 Hz - 3.0 kHz Frequency range
    Forced air ventilation
    M-roll surround and exponential cone geometry

    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.
