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.

Features 4-inch, fiberglass inside/outside copper voice coil 1700W continuous program power handling 100 dB Sensitivity 40 Hz - 2 kHz Frequency range Dual-forced air ventilation for minimum power compression Triple roll surround and exponential cone geometry Aluminum demodulation ring
