  • Incredibly linear frequency response characteristics, extreme high power handling while generating the lowest harmonic distortion of any comparable 18-inch transducer within its application range.

    Features :
    4-inch, fiberglass inside/outside copper voice coil
    2000W continuous program power handling
    97.5 dB Sensitivity
    25 Hz – 1 kHz Frequency range
    Progressive, spaced, aluminum demodulation rings
    Forced air ventilation and 14 mm top plate for minimum power compression
    Dual spider design with silicon based dampening control
    Triple roll surround and corrugated straight cone geometry

    The LF18X400 uses a fibre loaded cone assembly along with a high excursion triple roll, constant geometry surround. A fully optimised T-pole design generate the minimum amount of flux modulation. The T-pole also features RCF Precision's spaced gap demodulation technology, progressively braking the voice coil, providing a much smoother transition for the moving mass as it reaches its maximum excursion limits. Forced air venting system.

    Applications :
    The LF18X400 is ideal for use in applications where incredible power handling,long excursion and perfect control is required.
    Ideal for high quality professional bass reflex and bass-horn system.
    The transducer's low frequency extension, coupled with its extremely low generation of harmonic distortion,also makes it ideal for use within critical listening applications such as studio monitoring subwoofer system.
