The LS-218 is a high-performance dual 18-inch subwoofer engineered to extend low-frequency impact for large-format sound systems—whether stacked on the ground or flown in the air.
Equipped with two 18” direct-radiating LF drivers in a precisely tuned bass-reflex enclosure, LS-218 delivers massive SPL, deep punch, and low distortion even under extreme power. With support for standard or cardioid configurations, it gives you full control over low-frequency directivity for cleaner, more focused bass on stage.
Built from tour-grade birch plywood, the LS-218 is designed for demanding professional applications. It can be stacked horizontally, making it an ideal solution for concerts, festivals, and large-scale installations.
