Dual 8-inch round Vented / Bass-Reflex subwoofer box

Description

This 30 L Vented / Bass-Reflex enclosure is specifically designed for 2-driver 8-inch round subwoofers, tuned to 38 Hz. The cabinet features a Simple Rectangle shape constructed from 16 mm (5/8 inch) material with external dimensions of 577 × 299 × 299 mm (22.68 × 11.8 × 11.8 in). This versatile design serves as a general-purpose home subwoofer for music and stereo systems, balancing bass extension and size, while also being optimized for everyday car-audio use where trunk space and installation constraints are key. It utilizes one L-shaped slot port with an area suitable for high-output, large-excursion drivers and SPL applications requiring high airflow.
