The LF21N551 is very high power handling 21” neodymium woofer. The combination of a 3600 Watt power handling and a minimum weight of 13,7 Kg makes this transducer a unique product in his category. The transducer design is based on a very strong neodymium magnetic structure and a new 5,3” inside-outside copper coil. The new Dual forced design provide an excellent heat dissipation and lower power compression. Special air-forced ventilations are provided for voice coil, magnet assembly and basket. The combination of carbon fibre loaded cone assembly, large triple roll surround, double silicon spider provides to the LF21N551 remarkable strength and best control under large excursion conditions. A fully optimised T-pole design generate the minimum amount of flux modulation offering a peak to peak excursion of 72 mm. The waterproof body cone treatment and polycotton surround ensure a durable performance in every application.
