Description

This Vented / Bass-Reflex enclosure is designed for a single 8-inch round subwoofer, providing a 20 L chamber tuned to 38 Hz. Built from 16 mm (5/8 inch) material in a Simple Rectangle shape, the cabinet measures 548 × 281 × 234 mm (21.51 × 11.1 × 9.24 in). It features a double-thickness front baffle to increase rigidity and reduce flex, making it suitable for high-output systems. One L-shaped slot port is utilized, with a port area optimized for high-output drivers with increased cone excursion and airflow demand. This design serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, size, output, and low distortion. It is also ideal for everyday car-audio use, accounting for limited trunk space, installation constraints, and balanced sound.
