RCF LF15G401 - 15 inch 800W 8 Ohm part for EAW KF850 LC-1514
The LF15G401 is a 15-inch woofer with linear frequency response characteristics and very high power handling.
The LF15G401 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 52mm.
Applications:
The LF15G401 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 mechanical design and optimised weight of the device make it desirable for use in fixed installation or portable professional loudspeaker system.
Very good for 3 way, extended low frequency configurations.
