Dual 15-inch Round Vented Automotive Subwoofer Box - 130 L / 30 Hz - 1262 × 459 × 459 mm

This vented (bass-reflex) enclosure is designed for 2-driver 15-inch round subwoofer systems, utilizing a 130 L chamber tuned to 30 Hz. Built as a simple rectangle from 18 mm (3/4 inch) material, the external dimensions measure 1262 × 459 × 459 mm (50.38 × 18.1 × 18.1 in). The design features a double-thickness front baffle to increase rigidity and reduce panel flex, making it suitable for high-output subwoofer systems. For airflow, it uses one L-shaped slot port with an area optimized for high-output, large-excursion drivers and SPL-oriented use. This versatile box is ideal for everyday car audio, balancing trunk space and installation constraints, as well as general-purpose home stereo use where it maintains a balance between bass extension, size, and low distortion.
