Dual 8-inch rectangular bass-reflex automotive subwoofer box - 40 L / 38 Hz - 652 × 313 × 313 mm

This Vented / Bass-Reflex enclosure is specifically designed for a 2-driver 8-inch rectangular subwoofer setup. Constructed from 16 mm (5/8 inch) material in a simple rectangle shape, the cabinet features external dimensions of 652 × 313 × 313 mm (25.63 × 12.32 × 12.32 in). To accommodate high-output systems and reduce panel flex, the design includes a double-thickness front baffle for increased rigidity. The 40 L chamber is tuned to 38 Hz using one L-shaped slot port, which provides a port area suitable for high-output, large-excursion drivers and SPL applications with high airflow demand. Whether used as a general-purpose home subwoofer to balance bass extension and low distortion or for everyday car-audio use where trunk space and installation constraints are key, this box delivers balanced sound performance.
