Single 12-inch Rectangular Vented Subwoofer Box for Car Audio - 30 L / 38 Hz - 563 × 324 × 251 mm

This enclosure is designed for a single 12-inch rectangular subwoofer and features a 30 L chamber tuned to 38 Hz. The design uses a Vented / Bass-Reflex enclosure with one L-shaped slot port, providing a port area suitable for drivers with moderate cone excursion and airflow demand. Constructed from 16 mm (5/8 inch) material in a simple rectangle shape, the external cabinet dimensions are 563 × 324 × 251 mm (22.15 × 12.76 × 9.91 in). This design is intended for everyday car-audio use, balancing limited trunk space and installation constraints with a balanced sound. It also serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion.
