Single 15-inch Round Bass-Reflex Subwoofer Box for In-Vehicle - 65 L / 35 Hz - 672 × 432 × 313 mm

Description
This Vented / Bass-Reflex enclosure is designed for a single 15-inch round subwoofer, featuring a 65 L chamber tuned to 35 Hz. Built from 18 mm (3/4 inch) material in a simple rectangle shape, the external dimensions are 672 × 432 × 313 mm (26.89 × 17.04 × 12.36 in). This layout uses one L-shaped slot port positioned on the right side to maintain consistent visual alignment and ease of installation. The design is optimized for everyday car-audio use, balancing limited trunk space with high-quality sound. The port area is specifically suited for drivers with moderate cone excursion and airflow demand.
