Product information - RCF LF18X451

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.

Features 4,5 - inch fiberglas Inside/Outside copper voice coil 3600 Watt continuous program power handling 97 dB Sensitivity 30 Hz - 1 kHz Frequency range Dual Forced Hyperventing System Dual spider designed with silicon based damping control BL of 30.5 Txm to provide a faster and accurate low frequency
