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.
Features 4-inch, fiberglass inside/outside aluminum voice coil 1400W continuous program power handling 100 dB Sensitivity 40 Hz - 2 kHz Frequency range Dual spider design with silicon based dampening control Triple-roll surround and corrugated straight cone geometry Aluminum demodulation ring
