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

The JBL Professional PD544 is a high-performance 500W 15-inch passive 2-way horn-loaded installation loudspeaker designed for applications requiring precise pattern control, exceptional output capability, and superior sound quality. Featuring a 40 x 40-degree coverage pattern, this loudspeaker is optimized for venues demanding focused and intelligible sound projection, such as theaters, arenas, houses of worship, and large-scale auditoriums. Equipped with a powerful 2031H 15-inch low-frequency driver and a JBL 2432H 1.5-inch high-frequency compression driver, the PD544 delivers extended frequency response from 50 Hz to 20 kHz with low distortion and high clarity. Its sophisticated design allows it to operate in either bi-amp or passive mode, ensuring compatibility with diverse system configurations, while requiring digital signal processing for optimal performance.

The horn-loaded low-frequency driver enhances sensitivity and pattern control, ensuring consistent performance across the coverage area. The large-format rotatable PT Progressive Transition waveguide provides smooth frequency response and minimizes distortion, enabling flexible horizontal or vertical orientation for versatile installation options. Built to endure rigorous use, the PD544 features a trapezoidal enclosure constructed from 18 mm 11-ply Finnish birch plywood, coated in a rugged black DuraFlex finish for long-term durability. Its CE-compliant covered barrier strip terminals accept up to 10 AWG wire, ensuring secure and reliable connectivity. With its compact footprint and robust design, the PD544 integrates seamlessly into JBL's PD500 series, complementing full-range systems or functioning as a standalone solution for music and speech applications.

The PD544 is equipped with 22 M10 threaded suspension points for secure flown or ground-supported installations, making it ideal for permanent installations in demanding environments. Weather-resistant versions (WRC and WRX) are available for outdoor applications, including tropical or high-humidity environments. Its high sensitivity of 106 dB (passive mode) and peak SPL of 139 dB ensure powerful and clear sound reproduction in challenging acoustic spaces, while its switchable bi-amp/passive crossover modes offer system design flexibility. With JBL's legacy of engineering excellence, the PD544 is a trusted choice for precision audio performance in critical installations.
