12-inch Single Round Vented Car Subwoofer Box - 45L / 32Hz - 625 × 407 × 366 mm

This vented (bass-reflex) enclosure is designed for a single 12-inch round subwoofer, featuring a 45 L chamber tuned to 32 Hz. Built from 16 mm (5/8 inch) material in a simple rectangle shape, the cabinet measures 625 × 407 × 366 mm (24.55 × 16.03 × 14.43 in). To handle high-output subwoofer systems, it incorporates a double-thickness front baffle and one internal brace to increase rigidity and minimize panel vibration. The design utilizes one L-shaped slot port with an area suitable for high-output, large-excursion drivers and SPL-oriented applications with high airflow demands. It serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, size, output, and low distortion. Additionally, it is optimized for everyday car-audio use, accounting for limited trunk space, installation constraints, and balanced sound.
