Sound Barrier CORE10218SA — Active 18-Inch High Power Subwoofer
CORE10218SA Overview
The Sound Barrier CORE10218SA is an active 18-inch subwoofer system engineered for professional line array applications where high output and low-frequency extension are required in a compact, flyable enclosure. At its core is a single ultra-long-excursion 18-inch / 4-inch voice coil front-loaded woofer, with the rear of the low-frequency driver reflex loaded to extend output below the driver’s natural cutoff point. The onboard single-channel Class D amplifier is purpose-designed to power the companion CORE 10218SP passive cabinet, while also supporting full active line array configurations. The CORE10218SA is suited for touring companies, system integrators, and venues requiring a scalable, rigging-compatible subwoofer solution.
The CORE10218SA integrates the NUCLEUS FIR by Sound Barrier Loudspeaker Management Software via its latest digital signal processor, and its proprietary rigging system is directly compatible with the CORE 102A, CORE 102P, and CORE 10218SP for streamlined system assembly.
