Description

This vented (bass-reflex) enclosure is designed specifically for 2-driver 12-inch rectangular subwoofer systems. Built from 16 mm (5/8 inch) material with external dimensions of 963 × 398 × 398 mm (37.85 × 15.69 × 15.69 in), it features a simple rectangle shape. The 80 L chamber is tuned to 35 Hz using one L-shaped slot port, which offers a port area suitable for high-output, large-excursion drivers and SPL-oriented use with high airflow demand. A double-thickness front baffle increases cabinet rigidity and reduces front-panel flex, making the box ideal for high-output setups. This design is versatile enough for everyday car-audio use where trunk space and installation constraints matter, or as a general-purpose home subwoofer enclosure that balances bass extension, size, output, and low distortion.
