What is it?An 18” low-frequency driver for use in applications where both light weight and extreme power handling are required. DetailsSaid to offer “incredibly linear” frequency response characteristics and the highest power handling of any comparable 18” transducer, the LF18X401 features a fibre-loaded cone assembly along with a high-excursion triple roll, constant geometry surround. According to RCF, the design of the driver’s venting system guarantees efficient voice coil ventilation to minimise power compression and maintain power handling. Designed for touring systems in bass reflex and bass-horn enclosures, the LF18X401 incorporates a 4” fibreglass inside/outside copper voice coil capable of 2.4kW RMS power handling at a sensitivity of 98dB. Frequency response is quoted at 30Hz – 1kHz.
