Single 8-inch Vented / Bass-Reflex Subwoofer Box - 25 L / 38 Hz
Description
This simple rectangular cabinet, built from 16 mm (5/8 inch) material, is designed for a single 8-inch subwoofer. The 25 L chamber is tuned to 38 Hz using one L-shaped slot port, with a port area suitable for high-output drivers with increased cone excursion and airflow demand. Measuring 533 × 300 × 242 mm (20.94 × 11.83 × 9.54 in), it is ideal for everyday 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, perfectly balancing bass extension, cabinet size, output, and low distortion.
