Dual 12-inch Vented Car Subwoofer Box - 80 L / 32 Hz - 964 × 406 × 406 mm

Description
Designed for a 2-driver 12-inch round subwoofer, this vented (bass-reflex) enclosure features a simple rectangle shape constructed from 16 mm (5/8 inch) material. The 80 L chamber is tuned to 32 Hz using one L-shaped slot port with an area optimized for high-output, large-excursion drivers and SPL-oriented applications with high airflow demand. With external dimensions of 964 × 406 × 406 mm (37.9 × 15.99 × 15.99 in), it serves as a general-purpose home enclosure that balances bass extension, size, and low distortion, while also being suitable for daily car-audio use where trunk space and installation constraints are considered.
