Dual 15-inch rectangular vented subwoofer box for automotive - 130 L / 32 Hz - 1075 × 411 × 411 mm

Description
This Vented / Bass-Reflex enclosure is specifically designed for a 2-driver 15-inch rectangular subwoofer setup. Constructed from 18 mm (3/4 inch) material in a Simple Rectangle shape, the cabinet features external dimensions of 1075 × 411 × 411 mm (43 × 16.22 × 16.22 in). A double-thickness front baffle increases rigidity and reduces flex, making it ideal for high-output systems. The 130 L chamber is precisely tuned to 32 Hz using one L-shaped slot port with an area optimized for high-excursion drivers and high airflow demand. This design serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, size, and low distortion, while also being suitable for everyday car-audio use where trunk space and installation constraints are considered for balanced sound.
