Single 12-inch Round Vented / Bass-Reflex Subwoofer Box - 40 L / 35 Hz

This Vented / Bass-Reflex enclosure is designed for a single 12-inch round subwoofer. Built from 16 mm (5/8 inch) material in a Simple Rectangle shape, the cabinet measures 608 × 357 × 264 mm (23.91 × 14.09 × 10.41 in). It serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion. Additionally, it is optimized for everyday car-audio use by accounting for limited trunk space, installation constraints, and balanced sound. The design features a 40 L chamber tuned to 35 Hz and utilizes one L-shaped slot port. The port area is suitable for drivers with moderate cone excursion and airflow demand.
