The JBL AC299 is a high-performance 12-inch two-way loudspeaker engineered for fixed installation applications that demand a combination of high output, controlled dispersion, and weather-resistant durability. This speaker system integrates a powerful 12-inch woofer with a 1.5-inch exit compression driver, delivering robust full-range sound with exceptional clarity and efficiency suitable for foreground music and vocal reinforcement in a variety of environments. It is particularly suited for both indoor and covered outdoor installations such as auditoriums, fitness centers, transportation terminals, and large retail spaces where reliable, high-impact audio is necessary. The design focuses on providing consistent sonic performance and long-term reliability in commercially demanding settings.

A defining feature of the AC299 is its 90° by 90° constant-directivity horn, which provides symmetrical wide-angle dispersion for uniform sound coverage in square or difficult-to-cover spaces. The horn is precisely engineered to deliver smooth frequency response both on and off-axis, ensuring consistent tonal quality and superior intelligibility throughout the coverage area. This wide dispersion pattern is highly effective for applications where speakers need to cover broad audience areas from a centralized or corner-mounted location, minimizing the number of enclosures required for complete coverage and reducing problematic hot spots or dead zones.

Constructed for durability, the enclosure is built from void-free, moisture-resistant plywood and finished with a rugged, textured coating that protects against physical wear and environmental factors. The integrated rigging hardware includes multiple M10 threaded inserts, allowing for flexible and secure mounting options, including wall, ceiling, or pole mounting to meet specific installation needs. The speaker's crossover network utilizes high-quality components and incorporates protective circuitry to safeguard the transducers. With its blend of wide dispersion, high power handling, and a robust, installation-ready design, the JBL AC299 provides a versatile and powerful audio solution for commercial integrators seeking a reliable loudspeaker for demanding sound reinforcement tasks.
