The RCF LF15N401 is a high-power 15″ neodymium woofer designed for deep, controlled bass and minimal power compression. Its fiber-loaded cone, triple-roll surround, and dual spider construction ensure durability and precision. The advanced ventilation system keeps the voice coil cool, increasing efficiency and power handling, making it ideal for high-output applications.
