Single 12-inch Rectangular Vented / Bass-Reflex Subwoofer Box - 35 L / 35 Hz

This Vented / Bass-Reflex enclosure is designed for a single 12-inch rectangular subwoofer, featuring a 35 L chamber tuned to 35 Hz. Built from 16 mm (5/8 inch) material in a simple rectangle shape, the cabinet measures 612 × 388 × 349 mm (24.06 × 15.28 × 13.75 in). A double-thickness front baffle and one internal brace increase rigidity and reduce panel vibration, making it suitable for high-output systems. The design uses one L-shaped slot port with an area optimized for high-airflow demand and large-excursion drivers in SPL applications. This versatile box balances bass extension and low distortion for everyday car audio use where trunk space is limited, or as a general-purpose home subwoofer for stereo systems.
