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

Applications

The MB15N401 is ideal for use in applications where good power handling, very high efficiency and perfect linearity is required . It is the ideal 15" woofer for mid-bass application in 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.

  • 4-inch , fibreglass inside-outside copper voice coil
  • 1700 Watt continuous program power handling
