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

This simple rectangular cabinet is constructed from 18 mm (3/4 inch) material and is designed specifically for a single 8-inch round subwoofer. With external dimensions of 561 × 303 × 243 mm (22.59 × 11.98 × 9.6 in), the design is optimized for daily car-audio use where trunk space and installation constraints are key. It also serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion. The 25 L chamber is tuned to 35 Hz and features one L-shaped slot port. This port area is specifically suited for high-output drivers with increased cone excursion and airflow demand.
