Dual 12-inch Rectangular Vented / Bass-Reflex Subwoofer Box
Description
This Vented / Bass-Reflex enclosure is specifically designed for a 2-driver 12-inch rectangular subwoofer setup. Constructed from 16 mm (5/8 inch) material in a simple rectangle shape, the cabinet measures 922 × 396 × 396 mm (36.25 × 15.6 × 15.6 in). It features a 70 L chamber tuned to 35 Hz and utilizes one L-shaped slot port with an area optimized for high-output, large-excursion drivers and high airflow SPL demands. The design is ideal for everyday car-audio use where trunk space and installation constraints are factors, and it also serves as a general-purpose home subwoofer for music and stereo systems by balancing bass extension, cabinet size, output, and low distortion.
