Dual 10-inch Vented / Bass-Reflex Subwoofer Box - 70 L / 36 Hz

This simple rectangular enclosure is designed for 2-driver 10-inch rectangular subwoofer systems, constructed from 18 mm (3/4 inch) material with external dimensions of 888 × 372 × 372 mm (35.58 × 14.66 × 14.66 in). The 70 L chamber is tuned to 36 Hz using one L-shaped slot port, featuring a port area suitable for high-output, large-excursion drivers and SPL-oriented use with high airflow demand. For increased cabinet rigidity and reduced front-panel flex in high-output systems, the design includes a double-thickness front baffle. This versatile box balances bass extension, size, and low distortion for general-purpose home stereo use while remaining practical for everyday car-audio installations where trunk space and balanced sound are essential.
