Dual 12-inch Round Driver Vented / Bass-Reflex Subwoofer Box

This 80 L Vented / Bass-Reflex enclosure is designed for dual 12-inch round subwoofer drivers, featuring a chamber tuned to 35 Hz. Constructed from 16 mm (5/8 inch) material in a simple rectangle shape, the external dimensions are 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 daily car-audio use by considering installation constraints, limited trunk space, and balanced sound. The design incorporates one L-shaped slot port with a port area suitable for high-output, large-excursion drivers and SPL-oriented applications with high airflow demand.
