Description

This vented (bass-reflex) enclosure is designed for a single 15-inch round subwoofer, featuring a 85 L chamber tuned to 32 Hz. Constructed from 18 mm (3/4 inch) material in a simple rectangle shape, the cabinet measures 670 × 477 × 373 mm (26.85 × 18.81 × 14.7 in). It includes a double-thickness front baffle to increase rigidity and reduce flex, making it ideal for high-output systems. The design utilizes one L-shaped slot port with an area suitable for drivers with moderate cone excursion and airflow demand. This versatile enclosure balances bass extension, size, and low distortion for both everyday car-audio use in limited trunk spaces and general-purpose home stereo systems.
