  • 4 - inch, fiberglass inside-outside copper voice coil
  • 2400 Watt continuous program power handling
  • 98 dB Sensitivity
  • 30 Hz - 1 kHz Frequency range
  • Dual-forced air ventilation and 15mm top plate for minimum power compression
  • Dual spider design with silicon based dampening control
  • Triple-roll surround and corrugated straight cone geometry
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.
