Single 8-inch Vented / Bass-Reflex Subwoofer Box - 15 L / 38 Hz

This vented (bass-reflex) enclosure is designed for a single 8-inch round subwoofer, providing a 15 L chamber tuned to 38 Hz. It features a simple rectangle shape constructed from 16 mm (5/8 inch) material with external dimensions of 528 × 264 × 227 mm (20.73 × 10.4 × 8.94 in). A double-thickness front baffle increases cabinet rigidity and reduces front-panel flex, making the box suitable for high-output subwoofer systems. The design utilizes one L-shaped slot port with an area suitable for high-output drivers with increased cone excursion and airflow demand. This general-purpose home subwoofer enclosure for music and stereo systems balances bass extension, cabinet size, output, and low distortion while also being ideal for everyday car-audio use, accounting for limited trunk space, installation constraints, and balanced sound.
