RCF MB15H401 8/ohm

Reproduktor RCF 15", 700W, 100dB, 40-2000Hz, X-max 7,5mm, hmotnost 12,2kg

The MB15H401 is a 15-inch woofer with linear frequency response cheracteristics and very high efficiency.
The MB15H401 uses a fibre loaded exponential cone assembly along with a high excursion triple roll, constant geometry surround.
The fiberglass former, inside / outside aluminum voice coil provides a very good power handling maintaining light moving mass and proper Q for bass alignment.
Demodulation ring for fastest time response and lowest distortion.
