Dual 12-inch Rectangular Vented Subwoofer Box - 80 L / 32 Hz - 862 × 380 × 380 mm

This simple rectangle cabinet is designed for two 12-inch subwoofers and is constructed from 16 mm (5/8 inch) material. With external dimensions of 862 × 380 × 380 mm (33.88 × 14.98 × 14.98 in), the design accounts for limited trunk space, installation constraints, and balanced sound for everyday car-audio use. It also serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion. The vented (bass-reflex) enclosure features an 80 L chamber tuned to 32 Hz and utilizes one L-shaped slot port. The port area is specifically suited for high-output, large-excursion drivers and SPL-oriented applications with high airflow demands.
