RCF LF18G400

The LF18G400 is a 18-inch woofer with linear frequency response cheracteristics and very high power handling. The LF18G400 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. Special features of this 18" are the unique T-pole, curved against voice coil over-driving and 14mm top plate for best control and power handling.

Features 4-inch, fiberglass inside/outside copper voice coil 2000W continuous program power handling 97.5 dB Sensitivity 25 Hz - 1 kHz Frequency range T-pole, curved on top. 14mm top plate for minimum power compression Dual spider design with silicon based dampening control Triple-roll surround and corrugated straight cone geometry
