The LF15g401 is a 15-inch woofer with linear frequency response cheracteristics and very high power handling. The LF15G401 uses a fibre loaded cone assembly along with a high excursion triple roll, constant geometry surround. This combination provides remarkable strength and a peak to peak maximum excursion of 52mm.
Features 4-inch, fiberglass inside/outside copper voice coil 1600W continuous program power handling 97 dB Sensitivity 30 Hz - 1.5 kHz Frequency range Dual spider design with silicon based dampening control Triple-roll surround and corrugated straight cone geometry
