4-inch, fibreglass inside-outside copper voice coil
2000 Watt continuous program power handling
97.5 dB Sensitivity
25 Hz - 1 kHz Frequency range
T-pole, curved on top. 14 mm top plate for minimum power compression
Dual spider design with silicon based dampening control
Triple-roll surround and corrugated straight cone geometry
The LF18G400 is a 18-inch woofer with linear frequency response characteristics 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 a peak to peak maximum excursion of 50 mm. Special features of this 18 are the unique T-pole, curved against voice coil overdriving and the 14 mm top plate for best control and power handling.
Applications :
The LF18G400 is ideal for use in applications where incredible power handling, long excursion and perfect control is required. Ideal for high quality professional bass reflex and bass-horn systems. The robust mechanical design and optimised weight of the device make it desirable for use in fixed installation or portable professional loudspeaker systems
