Overview4-inch, fiberglass inside/outside copper voice coil 3000W continuous program power handling 96.5 dB Sensitivity 30 Hz – 1.5 kHz Frequency range Dual Forced Hyperventing System Dual spider design with silicon based dampening control Triple-roll surround and corrugated straight cone geometry Specifications
Very linear frequency response characteristics, extreme high power handling while generating the lowest harmonic distortion of any comparable 18-inch transducer within its application range. The LF15X401 uses a fibre loaded cone assembly along with a high excursion triple roll surround. This combination provides remarkable strength and a peak to peak maximum excursion of 50 mm. The new dual forced hyper-venting system guarantee a very efficient voice coil ventilation for minimum power compression and incredible power handling.
