Dual 10-inch Rectangular Ported Automotive Subwoofer Box - 70 L / 36 Hz - 810 × 357 × 357 mm

This Vented / Bass-Reflex enclosure is specifically designed for a 2-driver 10-inch rectangular subwoofer setup. Constructed from 16 mm (5/8 inch) material in a simple rectangle shape, the cabinet measures 810 × 357 × 357 mm (31.85 × 14.08 × 14.08 in). It features a 70 L chamber tuned to 36 Hz and utilizes a single L-shaped slot port with an area optimized for high-output, large-excursion drivers and high airflow SPL demands. The double-thickness front baffle increases overall rigidity and minimizes panel flex, making it ideal for high-power systems. Whether used as a general-purpose home subwoofer for music and stereo systems or for everyday car audio where trunk space and installation constraints are key, this design expertly balances bass extension, size, output, and low distortion.
