Automotive 15-inch Dual-Driver Rectangular Ported Subwoofer Box - 130 L / 30 Hz - 1262 × 459 × 459 mm

This Vented / Bass-Reflex enclosure is specifically designed for a 2-driver 15-inch rectangular subwoofer system. Built from 18 mm (3/4 inch) material in a Simple Rectangle shape, the cabinet features a double-thickness front baffle that increases rigidity and reduces flex for high-output setups. It utilizes a 130 L chamber tuned to 30 Hz with a single L-shaped slot port, offering a port area optimized for large-excursion drivers and high airflow SPL demands. The external dimensions are 1262 × 459 × 459 mm (50.38 × 18.1 × 18.1 in). This versatile design serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing extension and low distortion, while also remaining suitable for everyday car-audio use where trunk space and installation constraints are key.
