RCF LF18N401 The RCF LF18N401 features incredibly linear frequency response characteristics, the highest power handling of any comparable 18-inch neodymium transducer, and the lowest power compression. The LF18N401 uses a fiber 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 52mm. The unique Dual-forced air venting system guarantees very efficient voice coil ventilation for minimum power compression and higher power handling. Features: 4-inch inside/outside copper voice coil 2400 Watt continuous program power handling 98 dB Sensitivity 30Hz - 1kHz Frequency range Dual-forced air ventilation and 15 mm top plate for minimum power compression Dual spider design with silicon based dampening control Triple-roll surround and corrugated straight cone geometry Get Your RCF LF18N401 Today!
