DOWNLOAD DATA

The MB12N351 is designed to provide an excellent frequency response linearity with very low distortion.
A very strong neodymium magnetic structure guarantee dynamic and precision, a new and unique 3,5" voice coil design provides a very high power handling, especially recommended in comparison to a standard 3" voice coil. The unique Dual-forced air venting system guarantee a very efficient voice coil ventilation to minimize the power compression and provide higher power handling.

Applications

The MB12N351 is ideal for use in applications where a very high efficiency and linearity with high power handling is required. It's especially recommended for high powered multi-way system.

  • 3,5-inch, inside-outside copper voice coil
  • 1300 Watt continuous program power handling
  • 99 dB Sensitivity
  • 45 Hz - 3 kHz Frequency range
  • Dual-forced air ventilation for minimum power compression
  • Single spider design with silicon based damping control
