Description

This Vented / Bass-Reflex enclosure is designed for a single 15-inch rectangular subwoofer and features a 65 L chamber tuned to 32 Hz. Built from 18 mm (3/4 inch) material in a simple rectangle shape, the cabinet measures 688 × 435 × 315 mm (27.12 × 17.15 × 12.4 in) (W × H × D). The design incorporates one L-shaped slot port positioned on the right side for consistent installation and visual alignment. The port area is specifically suited for drivers with moderate cone excursion and airflow demand. Tailored for everyday car-audio use, this box balances sound quality with limited trunk space and installation constraints.
