IL PREZZO SI RIFERISCE AL SINGOLO WOOFER.
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 LF18X401 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.
