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

This vented (bass-reflex) enclosure is designed for two round 8-inch subwoofer drivers, balancing bass extension, cabinet size, output, and low distortion for both everyday car-audio use and general-purpose home stereo systems. The simple rectangle cabinet is constructed from 16 mm (5/8 inch) material with external dimensions of 608 × 299 × 299 mm (23.89 × 11.8 × 11.8 in). It features a 30 L chamber tuned to 38 Hz and one L-shaped slot port with an area suitable for high-output, large-excursion drivers and high-airflow SPL demands. To ensure suitability for high-power systems, a double-thickness front baffle increases rigidity and reduces flex while remaining compact enough for limited trunk space and installation constraints.
