RCF LF18G400 - 18" 1000W 8 Ohm

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.


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 system.
The robust machanical design and optimised weight of the device make it desiderable for use in fixed installation or portable professional loudspeaker system.
