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