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

This Vented / Bass-Reflex enclosure is designed for a single 8-inch rectangular subwoofer, featuring a 25 L chamber tuned to 35 Hz. Built from 16 mm (5/8 inch) material in a simple rectangle shape, the cabinet measures 578 × 303 × 243 mm (22.69 × 11.94 × 9.58 in). A double-thickness front baffle increases rigidity and reduces flex, making the box ideal for high-output subwoofer systems. It includes one L-shaped slot port with an area suitable for high-output drivers with increased cone excursion and airflow demand. This design serves as a general-purpose home subwoofer enclosure that balances bass extension, size, and low distortion, while also being optimized for everyday car-audio use where trunk space and installation constraints are key.
