RCF LF18N401 - 18" 1200W 8 Ohm

Incredibly linear frequency response characteristics, the highest power handling of any comparable 18-inch neodymium transducer, the lowest power compression.
The LF18N401 uses a fibre loaded cone assembly along with a high excursion triple roll,constant geometry surround.
This combination provides remarkablestrength venting system guarantee a very efficient voice coil ventilation for minimum power compression and higher power handling.


Applications:

The LF18N401 is ideal for use in applications where incredible power handling is required,long excursion and light weight.
Specially designedfor touring,perfect for high quality professional bass reflex and bass-horn system.
The transducers low frequency extension and control also makes it ideal for use within critical listening applications as studio monitoring subwoofer system.
