LF18N451

WOOFER

The LF18N451 is a very high power handling and efficiency transducer specially designed to provide powerful and accurate sub-bass frequencies with low distortion and low power compression.
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

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.
