Dual 12-inch Rectangular Bass-Reflex Car Subwoofer Box - 80 L / 35 Hz - 811 × 364 × 364 mm
Description
This simple rectangle cabinet, constructed from 16 mm (5/8 inch) material, is designed for a 2-driver 12-inch rectangular subwoofer. With external dimensions of 811 × 364 × 364 mm (31.88 × 14.35 × 14.35 in), the design prioritizes everyday car-audio use by balancing installation constraints and limited trunk space with high-quality sound. It also serves as a general-purpose home subwoofer enclosure for music and stereo systems, optimizing the balance between bass extension, cabinet size, output, and low distortion. The vented (bass-reflex) enclosure features an 80 L chamber tuned to 35 Hz and utilizes one L-shaped slot port. This port area is specifically suited for high-output drivers with increased cone excursion and airflow demand.
