Sound Barrier CORE8218SA-NHW — 18 Inch Active High Power Subwoofer
CORE8218SA Overview
The Sound Barrier CORE8218SA is an 18-inch active subwoofer system built for professional touring, installation, and live sound reinforcement applications. At its core is a 1500W Class D single-channel amplifier engineered to drive the corresponding CORE 8218SP passive cabinet, while also supporting full active line array configurations. The enclosure houses a single ultra-long 18-inch woofer with a 4-inch voice coil in a front-loaded, reflex-ported design that extends low-frequency output below the driver’s natural cutoff point. This system is suited for audio engineers, touring companies, and system integrators who require compact, high-output subwoofer solutions with flexible deployment options.
The CORE8218SA is designed for both flown and ground-stacked use, with a proprietary rigging system directly compatible with the CORE 82A, CORE 82P, and CORE 8218SP, and a threaded pole-mount socket on the top of the cabinet for use with the CORE82-BPSYS pole-mount and bracket system.
