Single 12-inch Vented / Bass-Reflex Subwoofer Box - 30 L / 35 Hz
Description
This vented (bass-reflex) enclosure is designed for a single 12-inch round subwoofer, featuring a 30 L chamber tuned to 35 Hz. Built from 16 mm (5/8 inch) material in a simple rectangle shape, the external dimensions are 611 × 359 × 264 mm (24.03 × 14.14 × 10.43 in). The design includes one L-shaped slot port with an area suitable for high-output drivers with increased cone excursion and airflow demand. This box is ideal for everyday car-audio use, balancing limited trunk space and installation constraints with a balanced sound. It also serves as a general-purpose home subwoofer enclosure for music and stereo systems, providing an optimal balance of bass extension, cabinet size, output, and low distortion.
