Dual 12-inch Vented / Bass-Reflex Subwoofer Box - 70 L / 35 Hz

This Vented / Bass-Reflex enclosure is specifically designed for a 2-driver 12-inch round subwoofer. The cabinet features a simple rectangle shape constructed from 18 mm (3/4 inch) material, with external dimensions of 954 × 398 × 398 mm (38.3 × 15.69 × 15.69 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 includes a 70 L chamber tuned to 35 Hz and utilizes one L-shaped slot port. This port area is perfectly suited for high-output, large-excursion drivers and SPL-oriented use with high airflow demand.
