Single 8-inch Vented / Bass-Reflex Subwoofer Enclosure - 25 L / 35 Hz

This Vented / Bass-Reflex enclosure is designed for a single 8-inch round subwoofer, featuring a 25 L chamber tuned to 35 Hz via one L-shaped slot port. Built from 16 mm (5/8 inch) material in a simple rectangle shape, the cabinet measures 522 × 292 × 239 mm (20.52 × 11.53 × 9.42 in). It is engineered for everyday car-audio use, balancing limited trunk space and installation constraints with balanced sound. Additionally, it serves as a general-purpose home subwoofer enclosure for music and stereo systems, optimizing bass extension, cabinet size, output, and low distortion. The port area is specifically suited for drivers with moderate cone excursion and airflow demand.
