Dual 12-inch Automotive Rectangular Ported Subwoofer Box - 80 L / 35 Hz - 834 × 364 × 364 mm

This Vented / Bass-Reflex enclosure is specifically designed for a 2-driver 12-inch rectangular subwoofer setup. Constructed from 18 mm (3/4 inch) material, the simple rectangle cabinet features external dimensions of 834 × 364 × 364 mm (33.35 × 14.36 × 14.36 in). It serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion. Additionally, it is optimized for everyday car-audio use by accounting for limited trunk space, installation constraints, and balanced sound. The design features an 80 L chamber tuned to 35 Hz and utilizes one L-shaped slot port. This port area is perfectly suited for high-output drivers with increased cone excursion and airflow demand.
