RCF LF21N451 21 Inch Professional Low Frequency Transducer [single]

This item is brand-new, factory sealed.

The LF21N451 is a very high power handling & efficiency transducer specially designed to provide powerful & accurate sub-bass frequencies w/low distortion & low power compression.
Ultra fast time response. The LF21N451 uses a fiber loaded cone assembly along a large triple roll surround, this combination provides remarkable strength & control. Double silicon spider system ensures excellent control during large excursions. A fully optimized 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.
The LF21N451 is ideal in applications where light weight, very high BL & power handling are required. It is especially used for touring, perfect for powerful lows in horn loaded sub bass system or reflex designs.
