JBL AC599 - 500W 15-inch Passive 2-Way Installation Loudspeaker with 90 x 90-Degree Coverage in Black Finish

The JBL Professional AC599 is a high-performance, full-range passive loudspeaker designed to deliver outstanding audio clarity and high output in both professional audio and fixed installation applications. Part of JBL's AE Application Engineered Series, this 500W speaker is engineered for venues requiring powerful, consistent sound across a wide frequency range. The AC599 features a 15-inch low-frequency driver and a 25 mm exit compression driver, producing deep bass and crisp highs with minimal distortion. The speaker is equipped with a rugged, black-textured finish, making it an ideal solution for demanding environments where both aesthetics and acoustics matter.

Designed for versatility, the AC599 provides a 90° x 90° coverage pattern, making it suitable for both vertical and horizontal applications. This broad coverage ensures even sound distribution across large areas, ideal for installations in auditoriums, stadiums, theaters, and other large spaces. The horn-loaded compression driver with a 35 mm (1.5-inch) voice coil ensures high power handling, while the high-slope passive crossover minimizes overlap and maintains a well-controlled off-axis response. As a result, the AC599 delivers clear, natural sound reproduction without any loss of intelligibility even at higher volumes.

With its durable design, the AC599 features a 15 mm multi-ply hardwood plywood enclosure, offering both acoustic performance and physical strength. The cabinet also includes four threaded inserts for MultiMount or similar mounting systems, allowing for easy integration into various mounting setups. Its multiple M10 suspension points further increase installation flexibility, making it suitable for both permanent and portable setups. The AC599 is built for reliable performance in a variety of professional audio applications, providing clear and powerful audio even in challenging environments.

The speaker also boasts impressive technical specifications. It features a frequency range of 60 Hz to 20 kHz (-10 dB) and a frequency response of 75 Hz to 18 kHz (±3 dB), ensuring it covers the full spectrum of audio. With a system sensitivity of 98 dB SPL at 1W/1m and a maximum SPL of 122 dB (128 dB peak), the AC599 can easily fill large spaces with high-output sound. The speaker is rated for long-term continuous power handling of 250W (IEC), 500W (program), and 1000W (peak), with a 2-hour power rating of 350W (1400W peak), ensuring reliability even under demanding conditions.

The AC599 is designed for professional use, and its versatile connectivity options include dual Neutrik NL4MP connectors and covered barrier strip terminals, making it easy to integrate into any sound system. Whether used as a main speaker or as part of a larger array, the AC599 ensures accurate sound reproduction with a minimal footprint, offering unparalleled performance for fixed installation applications.
