The SMACK 218 is a dual 18-inch passive sub bass system engineered for large-format reinforcement, where low-frequency energy must be felt as well as heard. Its birch-plywood acoustic shell and optimized internal airflow enhances efficiency, sound pressure level and long projection, translating 4000W of power into a 145dB max SPL that delivers a solid, deep, and controlled low end. Built for high performance and scale, it forms a reliable LF foundation for touring systems.
