MB12N301

MID - BASS

The MB12N301 is a neodymium, high efficiency, 12” mid-bass. High sensitivity, excellent linearity and very high power handling capabilities. The magnetic structure is powered by a large neodymium magnet that provides an extremely high flux density in the gap. The new hyper-vented aluminium basket and magnetic assembly design provide an excellent heat dissipation and lower power compression. Special air-forced ventilations are provided for voice coil, magnet assembly and basket. M-roll surround and spider design offer great linearity and precise reproduction.

Applications
  • • The very light moving mass and linear curve response make the MB12N301 the solution for high quality two or three way system.
  • • The aluminium voice coil guarantee a very high efficiency in conjunction to a proper Q factor for good bass response.
