The JBL PD595 is a professional, high-output horn-loaded full-range loudspeaker engineered for versatile sound reinforcement in demanding installed and touring applications. Its design centers on a 15-inch low-frequency driver integrated with a high-frequency compression driver mounted on a precision, constant-directivity horn. This configuration provides high acoustic efficiency, allowing the system to deliver significant sound pressure levels with exceptional clarity and dynamic range. The defining feature of this loudspeaker is its manually rotatable horn, which offers a 90° by 50° coverage pattern that can be oriented in either a horizontal or vertical configuration. This rotatability provides system designers and installers with critical flexibility to tailor the speaker's dispersion to the specific geometry of the audience area, making it ideal for applications in performing arts centers, houses of worship, large conference facilities, and live sound venues where coverage needs may vary.

Performance is characterized by powerful, articulate sound with controlled directivity. The horn-loaded design ensures that acoustic energy is directed precisely within the designated coverage pattern, minimizing unwanted reflections off walls and ceilings and thereby enhancing speech intelligibility and musical detail. The rotatable horn allows the wider 90° dispersion to be used horizontally for broad audience coverage or vertically for targeted, narrow coverage in balcony or deep-throw situations. As a passive system, the PD595 requires connection to an external amplifier and system processor. This enables the use of external digital signal processing (DSP) for precise crossover management, equalization, and driver protection, allowing for optimal integration within complex, multi-way sound systems and adaptation to specific room acoustics.

Constructed for professional durability, the enclosure is built from rugged, void-free plywood with a textured, scratch-resistant finish. It features multiple integrated rigging points, allowing for secure flying in arrays, cluster mounting, or placement on stage. The robust construction ensures reliable performance in both permanent installations and touring environments. By combining the high-output performance of a 15-inch horn-loaded system with the unique versatility of a rotatable horn, the JBL PD595 provides audio engineers and system integrators with a powerful and adaptable tool for delivering consistent, high-fidelity sound coverage in a wide variety of challenging acoustic spaces.
