Ground Shaker
30Hz Deep-Tuned Enclosure Built for Maximum SPL Impact

Built for extreme bass enthusiasts, this oversized enclosure delivers massive low-frequency power through its high-capacity internal chamber designed for maximum air movement and output. Tuned at a deep 30Hz, it produces powerful, chest-shaking bass that brings serious energy to any street or competition setup. A wide, high-flow slot port system enhances airflow efficiency while minimizing turbulence, resulting in stronger pressure, cleaner response, and earth-moving performance built for true bass lovers.

Built for Tight, Clean, High-Impact Bass Performance

Engineered for serious bass performance, this enclosure is crafted from dense, high-quality MDF to deliver exceptional strength, stability, and resistance against heavy vibration under extreme output. A reinforced front panel adds solid structural support, helping keep high-powered subwoofers stable for cleaner, more controlled bass response. With versatile mounting depth compatibility, it’s built to accommodate a range of performance subwoofers commonly used in both SPL and daily-driven audio systems.
