4-inch, fibreglass inside-outside copper voice coil
1800 Watt 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
The LF18G401 is a 18-inch woofer with linear frequency response characteristics 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 a peak to peak maximum excursion of 50 mm
Applications :
The LF18G401 is ideal for use in applications whereincredible 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.
