Single 12-inch Vented / Bass-Reflex Subwoofer Box - 45 L / 32 Hz

Designed for a single 12-inch round subwoofer, this Vented / Bass-Reflex enclosure features a 45 L chamber tuned to 32 Hz. The simple rectangle cabinet is constructed from 16 mm (5/8 inch) material with external dimensions of 599 × 407 × 366 mm (23.59 × 16.03 × 14.43 in). One internal brace reinforces the structure and reduces panel vibration, ensuring it is suitable for high-output systems. The design utilizes one L-shaped slot port with a port area optimized for large-excursion drivers and high-airflow SPL demands. Whether used as a general-purpose home subwoofer to balance bass extension and low distortion or for everyday car audio where trunk space and balanced sound are key, this box offers a versatile solution.
