RCF LF21N451

The LF21N451 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 LF21N451 uses a fibre loaded cone assembly along a large triple roll surround, this combination provides remarkable strength and control. Double silicon spider system ensures excellent control during large excursions. A fully optimised 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 98.5dB Sensitivity 30Hz - 1kHz Frequency range Dual-forced air ventilation for minimum power compression Dual spider designed with silicon based damping control BL of 34.5 T/m to provide a faster and accurate low frequency
