Single 12-inch Rectangular Vented Subwoofer Box for Vehicles - 45 L / 32 Hz - 683 × 426 × 311 mm

This Vented / Bass-Reflex enclosure is designed for a single 12-inch rectangular subwoofer, utilizing a 45 L chamber tuned to 32 Hz. Built from 16 mm (5/8 inch) material with a simple rectangle shape, the cabinet features external dimensions of 683 × 426 × 311 mm (26.86 × 16.78 × 12.27 in). A double-thickness front baffle increases rigidity and reduces flex, making it ideal for high-output systems. The design incorporates one L-shaped slot port positioned on the right side for consistent installation and visual alignment. This layout provides a port area suitable for high-output, large-excursion drivers and SPL-oriented use with high airflow demand. This enclosure is optimized for everyday car-audio use, balancing sound quality with limited trunk space and installation constraints.
