RCF LF18N451 - 18" 1500W 8 Ohm

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.
Its especially used for touring, perfect for powerful lows in horn loaded sub bass system or reflex designs.
