JBL PD525S-WH - 1000W 2 x 15-inch Passive Front Loaded Installation Subwoofer in White Finish

The JBL Professional PD525S-WH is a high-performance 1000W dual 15-inch passive front-loaded installation subwoofer designed to deliver exceptional low-frequency output in professional sound reinforcement applications. Featuring a sleek white finish, this subwoofer is built to integrate seamlessly with JBL's PD500 series loudspeakers, making it an ideal solution for venues requiring both aesthetic appeal and powerful bass performance. Equipped with two JBL 2275H Differential Drive 15-inch low-frequency drivers, the PD525S-WH delivers extended low-frequency response with minimal power compression and distortion, even at high output levels. Its frequency range of 28 Hz to 3.8 kHz and a peak SPL of 141 dB make it suitable for large venues, theaters, auditoriums, and houses of worship where impactful low-end performance is crucial.

The PD525S-WH's front-loaded, vented configuration is designed to ensure consistent low-frequency performance by minimizing port compression and maintaining clarity at high sound pressure levels. The trapezoidal enclosure, constructed from 18 mm 11-ply Finnish birch plywood, is both durable and acoustically optimized for low-frequency performance. Its 10-degree side angles allow for seamless integration into PD500 series arrays, enabling flexible system configurations. Finished in white DuraFlex, the enclosure blends into a variety of installations while providing long-lasting protection against wear and tear. For added versatility, the subwoofer includes 20 M10 threaded suspension points, making it suitable for flown or ground-supported setups. Input connectors feature CE-compliant barrier strip terminals that support up to 10 AWG wire, ensuring compatibility with professional audio systems.

The PD525S-WH is engineered for demanding installations where high-output low-frequency performance is required, offering reliability, flexibility, and exceptional sound quality. Optional weather-resistant versions (WRC and WRX) are available, expanding its usability to outdoor or extreme environments. Compact yet powerful, the PD525S-WH combines advanced engineering with practical design features, making it an essential component in any professional sound system where low-frequency extension and pattern control are critical.
