The MB10N251 is a 10” 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 M-roll surround shape combined to spider design offer good linear displacement and precise low frequency reproduction.
