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

This Vented / Bass-Reflex enclosure is designed for a single 12-inch round subwoofer. The simple rectangle cabinet is built from 16 mm (5/8 inch) material with external dimensions of 665 × 368 × 268 mm (26.12 × 14.5 × 10.56 in). It features a 35 L chamber tuned to 35 Hz using one L-shaped slot port, which provides a port area suitable for high-output drivers with increased cone excursion and airflow demand. A double-thickness front baffle increases cabinet rigidity and reduces front-panel flex, making the box ideal for high-output systems. This design is perfect for everyday car-audio use where trunk space and installation constraints are factors, and it also serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, size, output, and low distortion.
