Dual 8-inch Vented / Bass-Reflex Subwoofer Box - 30 L / 38 Hz

This vented (bass-reflex) enclosure is designed for two 8-inch rectangular subwoofer drivers, featuring a 30 L chamber tuned to 38 Hz. The cabinet has a simple rectangle shape built from 16 mm (5/8 inch) material with external dimensions of 577 × 299 × 299 mm (22.68 × 11.8 × 11.8 in). It utilizes one L-shaped slot port with an area suitable for high-output, large-excursion drivers and SPL-oriented use requiring high airflow. Designed for everyday car-audio use, it accounts for limited trunk space and installation constraints while providing a balanced sound. It also serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion.
