    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.

    • 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
