JBL PD525S Dual 15-inch Subwoofer – Black

JBL PD525S Dual 15-inch Subwoofer System

The JBL PD525S Dual 15-inch Subwoofer System is a high-output low-frequency loudspeaker engineered for professional sound reinforcement environments that demand powerful bass performance, reliability, and system scalability. Built around two 380 mm (15-inch) Dual Coil – Dual Gap Differential Drive® low-frequency drivers, the PD525S uses a front-loaded, vented acoustic configuration to deliver deep low-end extension, high efficiency, and exceptional power handling.

Designed for sports venues, performance spaces, auditoriums, and worship facilities, the PD525S provides authoritative bass reproduction with low-frequency extension down to 40 Hz and a wide operational bandwidth that supports both standalone subwoofer applications and integrated full-range system deployment. The Differential Drive® technology enhances thermal efficiency, reduces power compression, and maintains consistent output even under continuous high-power operation.

Its trapezoidal cabinet design ensures compatibility with all PD500 Series systems, allowing seamless array integration and consistent acoustic alignment in complex sound system deployments. Constructed from exterior-grade Finnish birch plywood, the enclosure delivers structural rigidity, acoustic stability, and long-term durability for both touring and fixed installations.

Flexible system configuration is supported through parallel and discrete input modes, enabling optimized amplifier matching and advanced system tuning. Multiple M10 threaded suspension points allow secure flown installation, while optional weather-resistant WRC and WRX versions support sheltered outdoor use or direct exposure in extreme environmental conditions. The JBL PD525S is engineered as a professional-grade subwoofer solution delivering deep bass authority, high output performance, and long-term operational reliability.
