The MB12N301 is neodymium, high efficiency, 12-inch mid-bass. High sensitivity, excellent linearity and very high power handling capabilities. The magnetic structure is powered by 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.
