Bring powerful, precise low-frequency reinforcement to your installed audio, paging and security systems with the JBL Professional AC118S 18" High Power Subwoofer System. Designed for pro installations, this subwoofer delivers the deep, controlled bass that enhances speech intelligibility for paging and alarm systems while adding impactful weight to program material used in surveillance and monitoring suites.
