Ultra fast time response. The LF18N451 uses a fibre loaded cone assembly along a large triple roll surround, this combination provides remarkable strength and control. Double silicon spider sysetm ensures excellent control during large excursions. A fully optimazed T-pole design generate the minimum amount of flux modulation.


The Dual-forced air venting system provides a very efficient voice coil ventilation to minimize the power compression

Features

  • 4,5 - inch Inside/Outside copper voice coil
  • 3000 Watt continuous program power handling
  • 97.5 dB Sensitivity
  • 30 Hz - 1 kHz Frequency range
  • Dual-forced air ventilation for minimum power compression
  • Dual spider designed with silicon based damping control
  • BL of 30.2 Txm to provide a faster and accurate low frequency

Applications

  • The LF18N451 is ideal in applications where light weight,very high BL and power handling are required.
  • It's especially used for tourimg,perfect for powerful lows in horn loaded sub bass system or reflex designs.
