Description

Sound Barrier CORE8218SP — 18-Inch Passive High Power Subwoofer

CORE8218SP Overview

The Sound Barrier CORE8218SP is a passive 18-inch sub-bass system built for professional live sound reinforcement, touring, and installed audio applications requiring high output and extended low-frequency performance. At its core is a single ultra-long-excursion 18-inch woofer with a 4-inch voice coil, front-loaded in a reflex-ported enclosure that extends low-frequency output below the driver’s natural cutoff point. The cabinet is designed primarily as a companion to the CORE 8218A active sub-bass cabinet, while remaining fully compatible with external rack-mount amplification for passive system configurations. Audio engineers, system integrators, and touring companies will find the CORE8218SP a versatile, deployment-ready solution for demanding sub-bass applications.

The CORE8218SP is compact and lightweight for its class, supporting both flown and ground-stacked deployment, and features a proprietary rigging system directly compatible with the CORE 82A, CORE 82P, and CORE 8218A cabinets for seamless system integration.

Key Features

  • 18-Inch Ultra-Long-Excursion Woofer — Single 18-inch driver with a 4-inch voice coil delivers high-output sub-bass performance with extended low-frequency reach
  • Front-Loaded, Reflex-Ported Enclosure — The woofer is front-loaded while the rear of the driver is reflex loaded, extending low-frequency output below the driver’s natural cutoff point
  • Passive Design with Flexible Amplification — Operates as a passive companion to the CORE 8218A active subwoofer or with rack-mount amplifiers in fully passive system configurations
  • Proprietary Rigging System — Directly compatible with the CORE 82A, CORE 82P, and CORE 8218A cabinets for integrated flown or ground-stacked arrays
  • Threaded Pole-Mount Socket — Top-mounted threaded socket accepts the CORE82-BPSYS pole-mount and bracket system for flexible speaker placement
  • Fly and Ground-Stack Ready — Compact, lightweight enclosure supports both flown and ground-stacked deployment to suit a wide range of venue configurations

About brand
Sound Barrier was founded in 1972 by George Mederos and until the late '90s, Sound Barrier manufactured quality affordable car audio equipment. For almost 30 years Sound Barrier grew to become one the most popular brands of Car Audio equipment in the Americas and the Caribbean. As the market shifted and the demand for secondary market car audio equipment faded, Sound Barrier forged a new path to success, developing a small line of entry-level professional audio equipment. There was nothing fancy about the new line, just a few good quality amps, and speaker cabinets.
