10-inch 2-Driver Rectangular Ported Subwoofer Box for Vehicles - 70 L / 36 Hz - 775 × 350 × 350 mm

This simple rectangular enclosure is built from 18 mm (3/4 inch) material and is designed for two 10-inch subwoofer drivers. The 70 L chamber is tuned to 36 Hz using one L-shaped slot port, which features a port area suitable for high-output drivers with increased cone excursion and airflow demand. Measuring 775 × 350 × 350 mm (31.03 × 13.8 × 13.8 in), the design is intended for everyday car-audio use where trunk space and installation constraints are balanced with sound quality. It also serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion.
