Single 10-inch Vented / Bass-Reflex Subwoofer Box - 30 L / 35 Hz

This Vented / Bass-Reflex enclosure is designed for a single 10-inch round subwoofer, balancing bass extension, cabinet size, and low distortion for both music systems and everyday car audio use. The simple rectangle cabinet is built from 18 mm (3/4 inch) material with external dimensions of 591 × 345 × 310 mm (23.7 × 13.63 × 12.26 in). It features a 30 L chamber tuned to 35 Hz and one L-shaped slot port with an area optimized for high-output, large-excursion drivers and high airflow SPL demands. One internal brace reinforces the structure and reduces panel vibration, ensuring it fits within limited trunk spaces while maintaining balanced sound.
