The MB15N301 is a neodymium, high efficiency, 15” mid-bass. High sensitivity, excellent linearity and very high power handling capabilities.

The magnetic structure is powered by a large neodymium magnet that provides an extremely high flux density in the gap. The new hyper-vented aluminium basket and magnetic assembly design provide an excellent heat dissipation and lower power compression. Special air-forced ventilations are provided for voice coil, magnet assembly and basket. M-roll surround and spider design offer great linearity and precise reproduction.

1000 Watt continuous program power handling
99 dB Sensitivity
40Hz –3.5KHz Frequency range
Dual-forced air ventilation for minimum power compression
