The LF18X451 18" Low Frequency Woofer from RCF offers a linear frequency response and high power handling while generating a low harmonic distortion. The LF18X451 uses a fiber loaded cone assembly along with a high excursion triple roll surround. This combination provides good strength and a peak-to-peak maximum excursion of 54mm. The dual forced hyper-venting system helps guarantee efficient voice coil ventilation for minimum power compression. A double silicon spider system helps ensure excellent control during large excursions. A fully optimized T-pole is designed to generate a minimum amount of flux modulation.
