RCF LF18G401

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.

Features 4-inch, fiberglass inside/outside copper voice coil 1800W continuous program power handling 98 dB Sensitivity 30 Hz – 1 kHz Frequency range Dual spider design with silicon based dampening control Triple-roll surround and corrugated straight cone geometry
