RCF MB15N401 8/ohm

Reproduktor RCF 15", 850W, 100dB, 40-2000Hz, X-max 5,5mm, hmotnost 7,5kg

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.
