Dual 15-inch Vented / Bass-Reflex Subwoofer Box - 130 L / 32 Hz

This vented (bass-reflex) enclosure is designed for 2-driver 15-inch round subwoofer units, featuring a 130 L chamber tuned to 32 Hz. Constructed from 18 mm (3/4 inch) material in a simple rectangle shape, the cabinet measures 1075 × 411 × 411 mm (43 × 16.22 × 16.22 in). The design incorporates a double-thickness front baffle to increase rigidity and reduce flex, making it ideal for high-output systems. It utilizes one L-shaped slot port with an area optimized for high-output drivers with increased cone excursion and airflow demand. This versatile enclosure serves as a general-purpose home subwoofer for music and stereo systems, balancing bass extension, size, output, and low distortion. Additionally, it is optimized for everyday car-audio use by accounting for limited trunk space, installation constraints, and balanced sound.
