The LF18G401 is a 18-inch woofer with linear frequency response cheracteristics and very high power handling.

The LF18G401 uses a fibre loaded cone assembly along with a high excursion triple roll, constant geometry surround.
This combination provides remarkable strength and peak to peak maximum excursion of 50mm.
