Single 8-inch Round Ported In-Vehicle Subwoofer Box - 20 L / 38 Hz - 544 × 264 × 237 mm

This Vented / Bass-Reflex enclosure is specifically designed for a single 8-inch round subwoofer. Built in a simple rectangle shape using 16 mm (5/8 inch) material, the cabinet features external dimensions of 544 × 264 × 237 mm (21.37 × 10.4 × 9.36 in). It includes one internal brace to reinforce the panels and reduce vibration, making it ideal for high-output subwoofer systems. The 20 L chamber is tuned to 38 Hz via one L-shaped slot port, which provides sufficient port area for drivers with high cone excursion and airflow needs. This design serves as a general-purpose home subwoofer for music and stereo systems, balancing bass extension and low distortion, while also being suitable for car audio applications where trunk space and installation constraints are key.
