Single 8-inch Vented / Bass-Reflex Subwoofer Box - 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. Built with 16 mm (5/8 inch) material in a simple rectangle shape, the external dimensions are 605 × 322 × 250 mm (23.77 × 12.69 × 9.88 in). A double-thickness front baffle increases rigidity and minimizes flex, making the cabinet ideal for high-output subwoofer systems. The box utilizes one L-shaped slot port with an area optimized for large-excursion drivers and high-airflow SPL applications. This design balances bass extension and size for general-purpose home stereo use while remaining compact enough for everyday car-audio installations with limited trunk space.
