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.
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
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.
