JBL PD544-WH - 500W 15-inch Passive 2-Way Horn Loaded Installation Loudspeaker with 40 x 40-Degree Coverage in White Finish

The JBL Professional PD544-WH is a 500W 15-inch passive 2-way horn-loaded installation loudspeaker designed for precision sound reinforcement in professional audio environments. Finished in an elegant white, this model combines powerful performance with aesthetic versatility, making it suitable for high-profile installations in theaters, worship spaces, and auditoriums. The PD544-WH delivers focused sound projection through its 40° x 40° coverage pattern, ensuring consistent and intelligible audio over large areas. Leveraging JBL's proprietary Precision Directivity technology, this loudspeaker is equipped with a rotatable PT Progressive Transition waveguide for smooth frequency response and flexible orientation, whether mounted vertically or horizontally.

The PD544-WH features a 2031H 15-inch horn-loaded low-frequency driver with a 3-inch voice coil, offering high sensitivity and low power compression for superior bass performance. The high-frequency range is handled by the JBL 2432H 1.5-inch exit compression driver, which uses a neodymium magnet and aluminum diaphragm to deliver clear, distortion-free audio even at high output levels. With a frequency range of 50 Hz to 20 kHz (-10 dB) and a maximum SPL of 139 dB, the PD544-WH ensures exceptional clarity and detail in music and speech applications. Designed for flexible system configurations, the loudspeaker supports both bi-amplified and passive modes, with a steep-slope passive crossover at 1.2 kHz for optimal performance. Digital signal processing is required to achieve its specified performance.

The PD544-WH's trapezoidal enclosure is crafted from 18 mm 11-ply Finnish birch plywood, ensuring durability and acoustic precision. The white DuraFlex finish not only enhances its visual appeal but also provides robust protection for long-term use. With 22 M10 threaded suspension points, this model offers versatile installation options, whether flown or ground-supported. Input connections are made through CE-compliant barrier strip terminals that support up to 10 AWG wire, ensuring compatibility with professional audio systems. The powder-coated 14-gauge perforated steel grille, backed by weather-resistant cloth, protects internal components while maintaining audio transparency. Optional weather-resistant versions (WRC and WRX) further expand its versatility for outdoor applications. The PD544-WH embodies JBL's legacy of innovation, offering powerful, precise, and reliable audio performance in a refined package.
