LF18N405
WOOFER
  • 4,0 - inch Inside/Outside copper voice coil
  • 3000 Watt continuous program power handling
  • 97.5 dB Sensitivity
  • 25Hz - 1kHz Frequency range
  • 4,0 - inch Inside/Outside copper voice coil
  • 3000 Watt continuous program power handling
  • 97.5 dB Sensitivity
  • 25Hz - 1kHz Frequency range
  • Hypervented magnetic structure for minimum power compression
  • Triple roll surround and exponential cone geometry
The LF18N405 is an extended low frequency with high power handling , designed to provide powerful and accurate bass frequencies with low distortion, low power compression and very high SPL. The LF18N405 uses a fibre loaded cone assembly along a large triple roll surround, this combination provides remarkable strength and control. The single spider system is specifically designed with a heavy cloth which ensures excellent control during large excursions. A fully optimised T-pole design generates the minimum amount of flux modulation. The Dual-forced air venting magnetic structure system provides a very efficient voice coil ventilation to minimize the power compression.
