Single 8-inch Round Vented / Bass-Reflex Subwoofer Box - 25 L / 38 Hz

This vented (bass-reflex) enclosure is designed for a single 8-inch round subwoofer and features a 25 L chamber tuned to 38 Hz. Built from 16 mm (5/8 inch) material in a simple rectangle shape, the external dimensions are 556 × 316 × 248 mm (21.84 × 12.48 × 9.8 in). The design uses one L-shaped slot port with a port area optimized for high-output, large-excursion drivers and SPL-oriented use requiring high airflow. It serves as a general-purpose home subwoofer enclosure for music and stereo systems by balancing bass extension, cabinet size, output, and low distortion. Additionally, it is suitable for everyday car-audio use, considering limited trunk space, installation constraints, and balanced sound.
