LF18-3600 18" Low Frequency Woofer Speaker — 8 Ohm, 4.5" Voice Coil

The LF18-3600 is an 18" low-frequency woofer engineered for tight, powerful bass response. It features a high BL at low frequency rated 30.5T-M to deliver controlled, deep, punchy low end. The driver uses a 4.5" diameter inside/outside copper voice coil mounted on a fiberglass former for reliable thermal handling and durability. Cooling is improved with forced air ventilation and a 15 mm top plate to reduce power compression under high power. A dual spider arrangement with silicon-based damping control maintains stable excursion and accurate damping. Mechanical durability and cone behavior come from a triple-roll surround paired with a corrugated straight cone geometry. The overall result is a speaker with good sensitivity, low distortion, and exceptional definition.
