Single 12-inch Round Vented / Bass-Reflex Subwoofer Box - 35 L / 35 Hz

This Vented / Bass-Reflex enclosure is specifically designed for a single 12-inch round subwoofer, featuring a 35 L chamber tuned to 35 Hz. Built from 16 mm (5/8 inch) material in a Simple Rectangle shape, the cabinet measures 575 × 345 × 310 mm (22.61 × 13.6 × 12.24 in). It incorporates one L-shaped slot port with a port area optimized for high-output drivers with increased cone excursion and airflow demand. One internal brace reinforces the structure and reduces panel vibration, making it ideal for high-output systems. This design is versatile enough for everyday car-audio use where trunk space is limited, or as a general-purpose home subwoofer for music and stereo systems, balancing bass extension, size, output, and low distortion.
