This subwoofer is engineered to complement JBL's full-range loudspeakers, providing the deep bass foundation required for music, live performance, and cinematic sound in venues such as nightclubs, performing arts centers, houses of worship, and entertainment complexes. It features a high-power 15-inch transducer with an optimized motor structure and large voice coil, capable of handling substantial amplifier power and delivering high sound pressure levels with low distortion and extended frequency response. The enclosure is constructed from rugged, void-free plywood and finished with a durable, textured coating for long-term durability.

The AC115S is designed for versatile deployment, offering multiple rigging and flying options to integrate seamlessly with main loudspeaker arrays or to be ground-stacked. Its tuned port design is optimized for maximum output and efficiency, ensuring powerful bass reproduction from the available amplifier power. The subwoofer's rugged input panel features dual Neutrik NL4 connectors for parallel wiring and flexible system integration. Built to meet the rigorous demands of professional use, the AC115S delivers the impactful, controlled bass necessary to create a full-range, immersive audio experience, supporting everything from subtle musical passages to explosive sound effects in a more compact format than an 18-inch model.

For system designers needing a powerful yet manageable low-frequency solution, the JBL AC115S provides an excellent balance of output, size, and flexibility. Its robust construction, high output capability, and flexible mounting options make it an ideal choice for enhancing the low-end performance of medium to large-scale professional audio systems.
