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

This vented (bass-reflex) enclosure is 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 external dimensions are 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 uses one L-shaped slot port with an area optimized for high-output, large-excursion drivers and SPL-oriented use with high airflow demand. It serves as a general-purpose home subwoofer enclosure for music and stereo systems by balancing bass extension, size, output, and low distortion. Additionally, it is ideal for everyday car-audio use, accounting for limited trunk space, installation constraints, and balanced sound.
