The MB8N251 is a 8” 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.
