8", 300W RMS, 600W program, 2.5" coil |
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. |
