Single 15-inch Rectangular Vented / Bass-Reflex Subwoofer Box - 85 L / 32 Hz

This vented (bass-reflex) enclosure is designed for a single 15-inch rectangular subwoofer, featuring an 85 L chamber tuned to 32 Hz. Built with a simple rectangle shape using 18 mm (3/4 inch) material, the external dimensions are 685 × 529 × 413 mm (27.4 × 20.88 × 16.31 in). A double-thickness front baffle increases cabinet rigidity and reduces front-panel flex, making the system ideal for high-output setups. The design utilizes one L-shaped slot port with an area suitable for high-output, large-excursion drivers and SPL-oriented use with high airflow demands. It serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion. It is also optimized for everyday car-audio use, considering limited trunk space, installation constraints, and balanced sound.
