IL PREZZO SI RIFERISCE AL SINGOLO WOOFER.
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.
