Single 12-inch Rectangular Vented / Bass-Reflex Subwoofer Box - 30 L / 38 Hz

This Vented / Bass-Reflex enclosure is designed for a single 12-inch rectangular subwoofer, featuring a 30 L chamber tuned to 38 Hz. Built from 16 mm (5/8 inch) material in a simple rectangle shape, the cabinet measures 601 × 351 × 262 mm (23.62 × 13.84 × 10.32 in). It serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion. For car-audio use, it accounts for limited trunk space, installation constraints, and balanced sound. The design utilizes one L-shaped slot port with a port area suitable for high-output drivers with increased cone excursion and airflow demand.
