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

This 80 L chamber Vented / Bass-Reflex enclosure is specifically designed for a 2-driver 12-inch rectangular subwoofer, tuned to 35 Hz for balanced performance. The cabinet features a simple rectangle shape constructed from 16 mm (5/8 inch) material with external dimensions of 845 × 376 × 376 mm (33.24 × 14.82 × 14.82 in). It serves as a general-purpose home subwoofer for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion. Additionally, it is optimized for everyday car-audio use, accounting for limited trunk space and installation constraints. The design incorporates one L-shaped slot port with an area suitable for high-output, large-excursion drivers and SPL-oriented use with high airflow demand.
