RCF MB12N405 - 12" 1000W 8 Ohm

The MB12N405 is a hypervented neo mid-bass design with a linear frequency response and very high efficiency.


To get this performance the magnetic structure use a high flux neo disc and the cone assembly a fibre loaded exponential shape along with a high excursion triple roll, constant geometry surround. The fibreglass former and aluminium voice coil provide a very high power handling maintaining a light mass and a proper Q factor for bass alignment.


Applications


  • The MB12N405 is ideal where is required extremely high power handling, very high efficiency and perfect linearity
  • Is the ideal 12" mid-bass woofer for reference high fidelity, high performance midbass application in compact 2 way system.

Features


  • 4-inch, fibreglass inside/outside aluminium voice coil
  • 2000W continuous program power handling
  • 98.5 dB Sensitivity
  • 50 Hz - 2 kHz Frequency range
  • Dual-forced air ventilation for minimum power compression
  • Triple roll surround and exponential cone geometry
