Description
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 external dimensions are 545 × 342 × 279 mm (21.42 × 13.49 × 11 in). The design uses one L-shaped slot port positioned on the right side to ensure visual alignment and installation consistency. The port area is specifically suited for drivers with moderate cone excursion and airflow demand. This box is ideal for everyday car-audio use, balancing limited trunk space and installation constraints with high-quality sound.
