JBL PD525S-WRC High-Output Dual 15″ Low-Frequency Subwoofer Loudspeaker with WRC Weather Protection

JBL PD525S-WRC Dual 15-inch Differential Drive Subwoofer System

The JBL PD525S-WRC Dual 15-inch Differential Drive Subwoofer System is a high-power, low-frequency loudspeaker engineered for professional sound reinforcement applications requiring deep bass performance, extreme output capability, and environmental durability. Built with two dual coil – dual gap Differential Drive® low-frequency transducers, the system utilizes a front-loaded, vented cabinet configuration that delivers powerful bass extension, high efficiency, and stable acoustic performance under continuous high-power operation.

Designed for demanding outdoor and semi-outdoor installations, the PD525S-WRC features a weather-resistant construction that ensures long-term reliability in exposed environments. Its trapezoidal enclosure design allows seamless integration with professional PA system arrays while providing structural rigidity and optimized acoustic loading. The low-frequency extension capability supports impactful sub-bass reproduction for large venues, open spaces, and high-energy sound systems.

The cabinet is constructed from high-strength birch plywood with a rugged perforated steel grille, providing both mechanical protection and acoustic transparency. The durable DuraFlex finish enhances resistance to wear, moisture, and environmental stress. Integrated M10 threaded suspension points enable secure flown installations, while the ground-stacking configuration supports flexible deployment options for touring and fixed installations.

With a passive design architecture, high sensitivity, and high SPL handling, the JBL PD525S-WRC delivers consistent, distortion-controlled bass output for professional audio systems. This subwoofer is ideally suited for outdoor PA systems, performance venues, event spaces, and large-scale sound reinforcement projects where reliability, power, and deep low-frequency performance are essential.
