JBL AC118S 18″ High-Power Subwoofer System – Black

JBL AC118S 18-inch subwoofer

The JBL AC118S is a high-power subwoofer system designed to deliver extended and controlled low-frequency reinforcement for professional fixed installation applications. Manufactured in China, it features a single 459 mm (18-inch) low-frequency driver integrated into a vented, front-loaded enclosure, enabling efficient airflow and consistent bass performance across a wide frequency range. This configuration supports deep low-end reproduction while maintaining clarity and stability at high sound pressure levels.

As part of JBL’s AE Application Engineered Series, the AC118S is engineered to serve a wide variety of permanent audio installations. The system provides natural and balanced low-frequency sound quality, making it suitable for environments where accurate bass reinforcement is required without overpowering the overall sound system. Its high-sensitivity design helps achieve higher output with reduced power compression, ensuring reliable performance during extended operation.

The enclosure is constructed from robust 18 mm multi-ply hardwood plywood, offering structural strength and long-term durability for fixed installations. A textured black paint finish provides a professional appearance while enhancing resistance to wear in demanding environments. The large front port design supports high acoustic output and reinforces low-frequency response with controlled distortion.

Installation flexibility is a key feature of the AC118S. The rectangular cabinet is equipped with multiple M10 threaded suspension points, allowing secure and versatile mounting options. This enables system designers to adapt placement according to room layout, acoustic requirements, and architectural constraints.

The AC118S is well suited for performing spaces, clubs and bars, houses of worship, multimedia environments, retail and hospitality spaces, presentation suites, and educational facilities where dependable and powerful low-frequency reinforcement is essential.
