Incredibly linear frequency response characteristics, the highest power handling of any comparable 18-in ch transducer, the lowest power compression.
The LF18X451 features a fiber loaded cone assembly along w/a high excursion triple roll, constant geometry surround: this combination provides remarkable strength & 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 & incredible power handling.
A double silicon spider system ensures excellent control during large excursions.
A fully optimized T-pole design generate the minimum amount of flux modulation.
