Single 12-inch Rectangular Subwoofer Vented / Bass-Reflex Box - 35 L / 35 Hz
Description
This vented (bass-reflex) enclosure is designed for a single 12-inch rectangular subwoofer, featuring a 35 L chamber tuned to 35 Hz. Built from 16 mm (5/8 inch) material in a simple rectangle shape, the external dimensions are 589 × 342 × 258 mm (23.16 × 13.49 × 10.19 in). This versatile box serves as a general-purpose home subwoofer enclosure 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. The design incorporates one L-shaped slot port with a port area suitable for drivers with moderate cone excursion and airflow demand.
