JBL AC118S-WH 18″ High-Power Subwoofer System – White

JBL AC118S 18-inch subwoofer

The JBL AC118S is a high-output subwoofer system developed to provide powerful and controlled low-frequency reinforcement for professional fixed installation environments. Manufactured in China, it incorporates a single 459 mm (18-inch) low-frequency driver mounted in a vented, front-loaded enclosure, allowing efficient airflow and stable bass performance across an extended frequency range. This design supports deep low-frequency extension while maintaining clarity and consistency at elevated sound pressure levels.

As a member of JBL’s AE Application Engineered Series, the AC118S is intended for a wide range of permanent audio installations. It delivers natural and balanced low-frequency sound quality, making it suitable for venues that require accurate bass reinforcement without compromising overall system intelligibility. The high-sensitivity system design minimizes power compression, enabling strong acoustic output with efficient use of amplifier power during long operating periods.

The enclosure is constructed from durable 18 mm multi-ply hardwood plywood, providing the structural strength required for long-term installations. The white painted finish offers a clean and refined appearance, making the subwoofer suitable for spaces where lighter-colored equipment is preferred to match architectural and interior design requirements. A large front port enhances low-frequency efficiency and supports high output with controlled distortion.

To accommodate varied installation needs, the rectangular cabinet is equipped with multiple M10 threaded suspension points. These attachment options allow secure mounting in different orientations, offering flexibility for system designers working with diverse room layouts and acoustic objectives.

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