Automotive 10-inch Single Rectangular Ported Subwoofer Box - 30 L / 38 Hz - 559 × 310 × 279 mm

This vented (bass-reflex) enclosure is designed for a single 10-inch rectangular subwoofer, featuring a 30 L chamber tuned to 38 Hz. Built from 16 mm (5/8 inch) material, the simple rectangle cabinet measures 559 × 310 × 279 mm (21.99 × 12.22 × 11 in) and includes one internal brace to reduce panel vibration for high-output systems. It utilizes one L-shaped slot port with an area suitable for high-output drivers with increased cone excursion and airflow demand. This design serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension and low distortion while remaining suitable for everyday car-audio use where trunk space and installation constraints require a balanced sound.
