Description

This vented (bass-reflex) enclosure is designed for a single 15-inch rectangular subwoofer, featuring a 65 L chamber tuned to 35 Hz. Constructed from 16 mm (5/8 inch) material in a simple rectangle shape, the cabinet measures 630 × 425 × 383 mm (24.78 × 16.77 × 15.09 in). The design incorporates a double-thickness front baffle and one internal brace to increase rigidity and reduce panel vibration, making it ideal for high-output systems. It utilizes one L-shaped slot port with an area suitable for high-output drivers with increased cone excursion and airflow demand. This versatile box serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, size, and low distortion, while also being optimized for everyday car-audio use where trunk space and installation constraints are key.
