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.
Key features :
2.5-inch , fibreglass former, aluminum voice coil
600 Watt continuous program power handling
96 dB Sensitivity
60 Hz - 3.5kHz Frequency range
Forced air ventilation
M-roll surround and exponential cone geometry
