RCF LF15G401 Woofer

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.
