Housed in a durable polypropylene enclosure with integrated handles, the J 15A is both portable and resilient, making it suitable for a variety of touring and installed sound environments. Its 380mm (15-inch) custom woofer ensures strong low-end performance, while the 25mm (1-inch) compression driver supports accurate high-frequency reproduction. The system features a constant directivity horn with a 90-degree horizontal by 60-degree vertical dispersion pattern, enabling consistent coverage across listening areas. Integrated digital signal processing includes dynamic equalisation, advanced protection, and four selectable presets that adapt the J 15A’s performance to different acoustic conditions. With multiple anchoring and suspension points, the J 15A is versatile in installation scenarios. Designed with reliability and clarity in mind, the J 15A Processed Active Monitor supports audio professionals in delivering high-quality sound with consistency and control in both portable and fixed setups.
