Sound Barrier CORE 10218SP Passive Subwoofer

Product Overview

The CORE10218SP is a passive 18″ sub-bass system engineered to deliver deep, powerful low-frequency performance for professional audio applications, including touring and installations. Designed for versatility, it can be used in conjunction with the CORE10218SA active subwoofer or as part of a fully passive setup with rack-mounted amplifiers.

Features

The CORE10218SP features a single ultra-long 18″ woofer with a 4″ voice coil and neodymium magnet, front-loaded and reflex-loaded at the rear to extend low-frequency output below the natural cutoff point. This design ensures high output capability and low-frequency extension. The system is compact and lightweight, allowing for both flown and ground-stacked configurations. Its proprietary rigging system is compatible with the CORE102A, CORE102P, and CORE10218SA, facilitating flexible deployment options.
