Dual 8-inch Vented / Bass-Reflex Subwoofer Box - 30 L / 38 Hz

This Vented / Bass-Reflex enclosure is designed for two 8-inch subwoofers, featuring a 30 L chamber precisely tuned to 38 Hz. The simple rectangular cabinet is constructed from 16 mm (5/8 inch) material with external dimensions of 670 × 321 × 321 mm (26.34 × 12.64 × 12.64 in). It includes a double-thickness front baffle that increases rigidity and reduces flex for high-output systems. For optimal airflow, the design utilizes one L-shaped slot port with an area suitable for large-excursion drivers and SPL applications. Whether used as a general-purpose home subwoofer for music and stereo systems or for everyday car audio where trunk space is limited, this box balances bass extension, size, and low distortion.
