Dual 8-inch Vented / Bass-Reflex Subwoofer Box - 30 L / 38 Hz

This vented (bass-reflex) enclosure is designed for 2-driver 8-inch round subwoofer units, utilizing a 30 L chamber tuned to 38 Hz. The simple rectangle cabinet features external dimensions of 670 × 321 × 321 mm (26.34 × 12.64 × 12.64 in) and is constructed from 16 mm (5/8 inch) material. A double-thickness front baffle increases rigidity and reduces panel flex, making this box ideal for high-output systems. It features one L-shaped slot port with an area suitable for large-excursion drivers and SPL applications with high airflow demand. Designed for versatility, it serves as a general-purpose home subwoofer enclosure for music that balances bass extension and low distortion, while also being optimized for car-audio use where trunk space and installation constraints are key.
