IL PREZZO SI RIFERISCE AL SINGOLO WOOFER.
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.
