  • 4,5 - inch fiberglas Inside/Outside copper voice coil
    3600 Watt continuous program power handling
    97 dB Sensitivity
    30 Hz - 1 kHz Frequency range
    Dual Forced Hyperventing System
    Dual spider designed with silicon based damping control
    BL of 30.5 Txm to provide a faster and accurate low frequency

    Incredibly linear frequency response characteristics, the highest power handling of any comparable 18-inch transducer, the lowest power compression.

    The LF18X451 features a fibre loaded cone assembly along with a high excursion triple roll, constant geometry surround: this combination provides remarkable strength and a peak to peak maximum excursion of 54 mm. The new dual forced hyper-venting system guarantee a very efficient voice coil ventilation for minimum power compression and incredible power handling. A double silicon spider system ensures excellent control during large excursions. A fully optimised T-pole design generate the minimum amount of flux modulation.

    APPLICATIONS
    - The LF18X451 is ideal in applications where combinations of incredible power handling, reasonable 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.
