The JBL AC28/26 is a compact yet powerful two-way loudspeaker system engineered for applications requiring wide, even coverage and high output from a relatively small enclosure. Its innovative design incorporates dual 8-inch low-frequency drivers working in tandem with a single high-frequency compression driver, a configuration that provides the acoustic output and bass extension typically associated with larger 15-inch cabinets while maintaining a significantly reduced footprint and weight. This makes it an exceptionally versatile solution for both permanent installation and portable sound reinforcement where space and weight are critical constraints. The system is defined by its asymmetrical, rotatable Constant Directivity horn, which provides a broad 120° by 60° dispersion pattern. This allows installers to rotate the horn to deploy the wider coverage angle either horizontally for audience coverage or vertically for front-fill or balcony applications, ensuring precise control over the sound field.

Constructed with durability as a priority, the AC28/26 features a rugged, multi-layered plywood enclosure finished with a durable, textured coating and protected by a heavy-duty steel grille. The cabinet design integrates multiple rigging points using industry-standard M10 threaded inserts, enabling flexible and secure mounting options including flying, wall-mounting, or stacking. Its high power handling and sensitivity allow it to produce substantial sound pressure levels with exceptional clarity and low distortion, making it capable of serving as a full-range main loudspeaker for music and speech in venues such as clubs, houses of worship, theaters, and performing arts centers. The coherent wavefront generated by the closely spaced dual woofers and the precisely aligned horn contributes to excellent pattern control and sonic accuracy across its entire operating bandwidth.

The loudspeaker’s internal passive crossover network utilizes high-quality components and is designed to provide optimal driver integration and protection. The voicing is tailored to deliver a balanced, articulate sound suitable for a wide range of program material, from reinforced music to spoken word. The combination of its unique dual-woofer design, wide and rotatable dispersion pattern, professional-grade components, and versatile rigging hardware establishes the JBL AC28/26 as a high-performance, space-efficient audio tool. It offers system designers a compelling alternative to bulkier traditional cabinets, providing powerful, controlled sound in environments where physical size and aesthetic integration are as important as acoustic performance.
