  • 3-inch, fibreglass inside/outside copper voice coil
  • 1000W continuous program power handling
  • 98.0 dB Sensitivity
  • 45 Hz – 2.5 kHz Frequency range
  • Dual Forced Hyperventing System
  • M-roll surround and exponential cone geometry
The MB12X301 is designed to provide an excellent frequency response linearity with very low distortion.
A strong magnetic structure guarantee dynamic and precision. The new dual forced hyper-venting system guarantee a very efficient voice coil ventilation for minimum power compression and incredible power handling. M-roll surround, exponential cone geometry and spider design offer great linearity and precise reproduction.
