Take your bass to the next level with the Ground Shaker GS-W7P113B Black 13" Single Ported Subwoofer Enclosure, engineered specifically for the legendary JL Audio 13W7. Unlike generic prefab boxes, this reinforced enclosure is built to the exact specifications needed to unleash the full potential of your subwoofer. With 2.37 cubic feet of air space and a 35 Hz tuning frequency, you'll experience deeper lows, harder-hitting bass, and the kind of output serious car audio enthusiasts demand.
Constructed from premium 3/4" MDF with a reinforced 1-1/4" front baffle, this ported subwoofer box is designed to handle the power and excursion of the JL Audio 13W7. The durable trunk liner finish resists everyday wear, while high-quality Titebond wood glue and silicone sealing help eliminate unwanted vibrations and air leaks. From daily driving to weekend demos, this enclosure delivers the strength and reliability needed for high-performance car audio systems.
If you've invested in a JL Audio W7, don't hold it back with an undersized or poorly designed enclosure. The Ground Shaker GS-W7P113B is optimized to maximize bass response, improve efficiency, and deliver the low-frequency impact that makes every song come alive. Whether you enjoy hip-hop, EDM, rock, or competition-style demos, this 13-inch ported subwoofer enclosure provides the powerful, accurate bass performance that transforms an ordinary system into an unforgettable listening experience.
