Single 12-inch Round Vented Car Subwoofer Box - 35 L / 35 Hz - 586 × 388 × 349 mm

Designed for a single 12-inch round subwoofer, this Vented / Bass-Reflex enclosure features a 35 L chamber tuned to 35 Hz. The cabinet is constructed from 16 mm (5/8 inch) material in a simple rectangle shape with external dimensions of 586 × 388 × 349 mm (23.06 × 15.28 × 13.75 in). One internal brace reinforces the cabinet and reduces panel vibration, making it 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 applications. This versatile box is engineered for everyday car-audio use with limited trunk space and balanced sound, while also serving as a general-purpose home subwoofer for music and stereo systems that balances bass extension, size, and low distortion.
