Dual 12-inch Rectangular Vented / Bass-Reflex Subwoofer Box

This Vented / Bass-Reflex enclosure is specifically designed for a 2-driver 12-inch rectangular subwoofer setup, balancing bass extension, cabinet size, and low distortion. Constructed from 16 mm (5/8 inch) material in a simple rectangle shape, the cabinet measures 826 × 363 × 363 mm (32.48 × 14.3 × 14.3 in). It features a 60 L chamber tuned to 35 Hz and utilizes one L-shaped slot port with an area optimized for high-output, large-excursion drivers and high-airflow SPL demands. The double-thickness front baffle increases rigidity and reduces flex, making it suitable for high-output systems. Whether used as a general-purpose home subwoofer for stereo systems or for everyday car-audio where trunk space and installation constraints are key, this design delivers balanced sound.
