  • 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.

    Features :
    4,5 - inch Inside/Outside copper voice coil
    3000 Watt 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 with silicon based damping control
    BL of 34.5 Txm to provide a faster and accurate low frequenc

    The height of the voice coil has been specifically designed to improve the excursion and linearity at very low frequencies.
    The LF21N451 uses a special RCF developed carbon fibre + nylon + cellulose composite pulp which reinforces and improves the rigidity of the cone structure.
    The new pulp and the large triple roll surround along double silicon spider system ensure excellent control and makes the cone resistant to deformation caused by very large displacements and pressure created by the transducer's high excursion behaviour.
    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.

    Applications :
    The LF21N451 is ideal in applications where light weight,very high BL and power handling are required.
    It's especially used for tourimg,perfect for powerful lows in horn loaded sub bass system or reflex designs.
