DESCRIPTION DU PRODUIT | GARANTIE | |
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. Applications : * • The MB8N251 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.
