MB10N251

MID - BASS

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.

Applications
  • • The MB10N251 finds its application in compact 2-way bass reflex system where very high dynamic and power handling are required.
  • • Perfect for multi-way reflex enclosures such as line arrays.
