Single 8-inch Vented / Bass-Reflex Subwoofer Box - 25 L / 35 Hz

This vented (bass-reflex) enclosure is designed for a single 8-inch rectangular subwoofer and features a 25 L chamber tuned to 35 Hz. Built from 18 mm (3/4 inch) material, the simple rectangular cabinet has external dimensions of 581 × 303 × 273 mm (23.36 × 11.97 × 10.77 in). One internal brace reinforces the cabinet and reduces panel vibration, making it ideal for high-output systems. The enclosure uses one L-shaped slot port with an area suitable for high-output, large-excursion drivers and SPL-oriented use requiring high airflow. It serves as a general-purpose home subwoofer for music and stereo systems, balancing bass extension, size, and low distortion, while also being suitable for car-audio use where trunk space and balanced sound are priorities.
