Dual 12-inch Vented / Bass-Reflex Subwoofer Box - 60 L / 35 Hz

This vented (bass-reflex) enclosure is specifically designed for a 2-driver 12-inch rectangular subwoofer. The simple rectangle cabinet is constructed from 18 mm (3/4 inch) material with external dimensions of 815 × 363 × 363 mm (32.61 × 14.34 × 14.34 in). Featuring a 60 L chamber tuned to 35 Hz and a single L-shaped slot port, the design provides a port area ideal for high-output, large-excursion drivers and SPL applications requiring high airflow. It serves as a balanced general-purpose home subwoofer enclosure for music and stereo systems, optimizing bass extension, size, and low distortion, while also remaining suitable for everyday car-audio use where trunk space and installation constraints are key.
