Description
This Vented / Bass-Reflex enclosure is designed for a single 12-inch rectangular subwoofer, featuring a 45 L chamber tuned to 32 Hz. Built from 16 mm (5/8 inch) material in a Simple Rectangle shape, the external cabinet dimensions are 584 × 374 × 292 mm (22.97 × 14.75 × 11.5 in). The layout includes one L-shaped slot port positioned on the right side to keep location consistent for installation and visual alignment. The port area is suitable for drivers with moderate cone excursion and airflow demand. This design is optimized for everyday car-audio use, balancing sound quality with limited trunk space and installation constraints.
