The RCF L18P300 is a high-power 18-inch woofer designed for deep, accurate bass reproduction. With a 4-inch fiberglass inside/outside copper voice coil and 2000W program power handling, it delivers low-frequency performance with minimal distortion. Its dual spider design with silicone-based dampening control ensures excellent stability, while forced air ventilation and a 15mm top plate minimize power compression. The M-roll surround and exponential cone geometry enhance durability and efficiency, making it ideal for bass reflex and bandpass systems.
