Single 15-inch Round Bass-Reflex Subwoofer Box - Right Port, 85 L / 32 Hz - 669 × 495 × 374 mm

Description

This vented (bass-reflex) enclosure is designed for a single 15-inch round subwoofer, featuring an 85 L chamber tuned to 32 Hz. Built from 18 mm (3/4 inch) material in a simple rectangle shape, the cabinet measures 669 × 495 × 374 mm (26.74 × 19.52 × 14.76 in). Its layout includes a single L-shaped slot port positioned on the right side to ensure consistent installation and visual alignment. This design is optimized for everyday car-audio use, balancing limited trunk space and installation constraints with high-quality sound. The port area is specifically suited for high-output drivers with increased cone excursion and airflow demand.
