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. 4.5-inch inside/outside copper voice coil. 3000 W continuous program power handling. 98.5 dB sensitivity. 30 Hz - 1 kHz frequency range. Dual-forced air ventilation for minimum power compression. Dual spider designed w/silicon based damping control. BL of 33.5 T/m to provide a faster accurate low frequency
