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

This Vented / Bass-Reflex enclosure is specifically designed for 2-driver 12-inch rectangular subwoofers, featuring a 70 L chamber tuned to 35 Hz. Constructed from 16 mm (5/8 inch) material in a simple rectangle shape, the cabinet measures 852 × 369 × 369 mm (33.49 × 14.55 × 14.55 in). The double-thickness front baffle significantly increases rigidity and reduces flex, making it ideal for high-output systems. It utilizes one L-shaped slot port with a port area optimized for large-excursion drivers and high-airflow SPL demands. Whether used as a general-purpose home subwoofer for music and stereo systems or in everyday car-audio applications, this design balances bass extension, output, and low distortion while respecting limited trunk space and installation constraints.
