RCF LF18N401

18-inch neodymium woofer with 8 ohm impedance, rated at 1200W AES power handling and 2400W program power. Sensitivity of 98 dB across a 30 Hz to 1 kHz frequency range. Built with a 4-inch fiberglass inside-outside copper voice coil, fiber-loaded cone assembly, and high-excursion triple-roll constant geometry surround. Dual-forced air ventilation and a 15mm top plate minimize power compression, while a dual spider design with silicon damping allows maximum excursion of 52mm peak-to-peak. Net weight 9.1 kg.
