Dual 12-inch Vented / Bass-Reflex Subwoofer Enclosure

This Vented / Bass-Reflex enclosure is specifically designed for dual 12-inch subwoofer drivers within a 60 L chamber tuned to 35 Hz. Built from 18 mm (3/4 inch) material, the simple rectangular cabinet features external dimensions of 856 × 363 × 363 mm (34.32 × 14.34 × 14.34 in). To handle high-output systems and reduce panel flex, the design includes a double-thickness front baffle. It utilizes one L-shaped slot port with a surface area optimized for high-airflow demand and large-excursion drivers. This versatile box is engineered for everyday car audio use, fitting within limited trunk constraints, while also serving as a high-performance home stereo subwoofer that balances bass extension, size, and low distortion.
