LF18X451
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.
Applications
- • The LF18X451 is ideal in applications where combinations of incredible power handling, reasonable weight and ultra fast time response are required.
- • Perfect for powerful lows in horn loaded sub bass systems or reflex designs.
- • Ideal for touring, find a perfect application in high power, heavy duty, club subwoofer systems.
