The QSC AD-DWL.SUB is a compact outdoor landscape subwoofer designed to deliver enhanced low-frequency performance in distributed audio systems. Equipped with a 5.25-inch (135 mm) weather-resistant cone woofer, it provides tight, musical bass reinforcement while maintaining a discreet, landscape-friendly appearance. With a reliable 120W 70/100V transformer and 16Ω bypass option, it offers flexible integration into both high- and low-impedance systems, achieving a maximum peak SPL of 112 dB (16Ω bypass).

Built for durability, the rugged F1-F2 UL-rated polypropylene and fiberglass enclosure is engineered to withstand outdoor environments, while tamper-resistant stainless-steel hardware ensures secure installation. It includes a direct-to-concrete mounting collar, with an optional burial mounting solution available via the AD-DWL.BASE accessory. Finished in an unobtrusive green color that blends naturally into landscaping—and featuring a paintable exterior for custom applications—the AD-DWL.SUB meets IP55 standards for dust and splash resistance, making it ideal for parks, hospitality venues, and commercial outdoor spaces.
