Single 12-inch Rectangular Vented / Bass-Reflex Subwoofer Box

This Vented / Bass-Reflex enclosure is designed for a single 12-inch rectangular subwoofer and features a 35 L chamber tuned to 35 Hz. Built from 16 mm (5/8 inch) material in a simple rectangle shape, the external dimensions are 625 × 368 × 268 mm (24.58 × 14.5 × 10.56 in). It uses one L-shaped slot port with a port area suitable for high-output drivers requiring increased cone excursion and airflow. The design is ideal for everyday car-audio use, considering limited trunk space and installation constraints, as well as a general-purpose home subwoofer for music and stereo systems where it balances bass extension, cabinet size, output, and low distortion.
