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

This 35 L vented (bass-reflex) enclosure is expertly designed for a single 12-inch round subwoofer, tuned precisely to 35 Hz. Built from 16 mm (5/8 inch) material in a simple rectangle shape, the cabinet features external dimensions of 612 × 388 × 349 mm (24.06 × 15.28 × 13.75 in). To accommodate high-output subwoofer systems, it includes a double-thickness front baffle and one internal brace to maximize rigidity and minimize panel vibration. Airflow is managed via one L-shaped slot port with an area optimized for large-excursion drivers and high-demand SPL applications. This versatile box serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, size, and low distortion, while also being suitable for daily car-audio use where trunk space and installation constraints are key.
