MB15N401

MID - BASS

The MB15N401 is a neo midbass with a linear frequency response and very high efficency.
To get this performance the magnetic structure use a demodulation ring and a fibre loaded exponential cone assembly along with a high excursion triple roll, constant geometry surround.
The fibreglass former, inside / outside copper voice coil provides a very good power handling maintaining a light mass and a proper Q factor for bass alignment.
The demodulations ring guarantee a fastest time response and lowest distortion.

Applications
  • • The MB15N401 is ideal for use in applications where is required good power handling, very high efficiency and perfect linearity.
  • • Is the ideal 15" woofer for mid-bass application in the compact 2 way system.
  • • The robust mechanical design and optimised weight of the device make it desirable for use in fixed installation or portable professional loudspeaker system
