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

This 35 L Vented / Bass-Reflex enclosure is designed for a single 12-inch round subwoofer and is tuned to 35 Hz. The cabinet features a simple rectangle shape constructed from 16 mm (5/8 inch) material with external dimensions of 589 × 342 × 258 mm (23.16 × 13.49 × 10.19 in). It utilizes one L-shaped slot port with an area suitable for drivers with moderate cone excursion and airflow demand. This design serves as a general-purpose home subwoofer for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion. It is also optimized for everyday car-audio use, accounting for limited trunk space, installation constraints, and balanced sound.
