Single 8-inch Round Vented / Bass-Reflex Subwoofer Box - 25 L / 35 Hz

This vented (bass-reflex) enclosure is specifically designed for a single 8-inch round subwoofer. Built from 16 mm (5/8 inch) material in a simple rectangle shape, it features external dimensions of 539 × 303 × 243 mm (21.18 × 11.94 × 9.58 in). The 25 L chamber is precisely tuned to 35 Hz using one L-shaped slot port. The port area is optimized for high-output drivers with increased cone excursion and airflow demand. Whether used as a general-purpose home subwoofer for music and stereo systems or in a car-audio setup where trunk space and installation constraints are key, this design expertly balances bass extension, cabinet size, output, and low distortion for a balanced sound.
