LF18N401

WOOFER

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 transducer's low frequency extension and control also makes it ideal for use within critical listening applications as studio monitoring subwoofer system.
