Single 15-inch Round Vented / Bass-Reflex Subwoofer Box - 85 L / 32 Hz

This Vented / Bass-Reflex enclosure is designed for a single 15-inch round subwoofer and features a 85 L chamber tuned to 32 Hz. Constructed from 18 mm (3/4 inch) material in a simple rectangle shape, the cabinet measures 674 × 495 × 387 mm (26.99 × 19.52 × 15.25 in). The design includes a double-thickness front baffle to increase rigidity and reduce flex, making it ideal for high-output subwoofer 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 enclosure is optimized for daily car-audio use with limited trunk space and installation constraints, as well as general-purpose home stereo systems, balancing bass extension, cabinet size, output, and low distortion.
