  • 3600 Watts continuous prgram power handling
    5.3 inch Inside/Outside copper voice coil
    97 dB Sensivity
    30 Hz - 1 kHz Frequency range
    Dual-forced air ventilation
    Dual spider designed with silicon based damping control
    72 mm peak to peak excursion
    39 T/m BL

    The LF21N551 is very high power handling 21" neodymium woofer. The combinaison of a 3600 Watts 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 combinaison 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 doby cone treatment and polycotton curround ensure a durable performance in every application.

    Applications :
    The LF21N551 is ideal in applications where combinations of maximum power handling, light weight and ultra fast time response are required.
    Perfect for powerful lows in horn loaded sub bass systems or reflex designs. Ideal for touring, find a perfect application in high power, heavy duty, club subwoofer systems.

Quality
Note: 4.5/5 Commentaire: Heya. Missed the oportunity by a hair to buy LF21N551 from here at nice price, but at least I have a recommendationt for further purchases.

For the price here, it seems to be unbeatable. Very nice strong driver, low thermal compression, does let one to push it to 20mm of cone excursion. Only downside is that it has rather loud cooling noises from magnet. So it is not suited for ULF home cinema. Other than that, GET IT. :-)
