Dual 8-inch Vented / Bass-Reflex Subwoofer Box - 40 L / 38 Hz
Description
This Vented / Bass-Reflex enclosure is specifically designed for a 2-driver 8-inch rectangular subwoofer. Built from 16 mm (5/8 inch) material, the cabinet features a simple rectangle shape with external dimensions of 620 × 313 × 313 mm (24.37 × 12.32 × 12.32 in). It serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, size, output, and low distortion. Additionally, it is optimized for everyday car-audio use, considering limited trunk space, installation constraints, and balanced sound. The 40 L chamber is tuned to 38 Hz using one L-shaped slot port. The port area is suitable for high-output, large-excursion drivers and SPL-oriented use with high airflow demand.
