Description

This Vented / Bass-Reflex enclosure is designed for a single 15-inch rectangular subwoofer and features a 65 L chamber tuned to 33 Hz. Constructed from 16 mm (5/8 inch) material in a Simple Rectangle shape, the cabinet measures 633 × 430 × 387 mm (24.9 × 16.94 × 15.24 in). A double-thickness front baffle and one internal brace increase rigidity and reduce panel vibration, making it suitable for high-output subwoofer systems. The design uses one L-shaped slot port with an area optimized for high-output drivers with increased cone excursion and airflow demand. This versatile enclosure is ideal for everyday car-audio use, balancing installation constraints and trunk space, or as a general-purpose home subwoofer box that optimizes bass extension and output with low distortion.
