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

This enclosure is designed for a single 8-inch rectangular subwoofer, utilizing a Vented / Bass-Reflex design with a 25 L chamber tuned to 35 Hz. Built from 18 mm (3/4 inch) material in a simple rectangle shape, the external dimensions are 595 × 323 × 251 mm (23.72 × 12.77 × 9.91 in). It features one L-shaped slot port with an area suitable for high-output, large-excursion drivers and SPL-oriented use requiring high airflow. The design is ideal for everyday car-audio use, balancing installation constraints and limited trunk space with balanced sound, while also serving as a general-purpose home subwoofer enclosure for music and stereo systems that optimizes bass extension, cabinet size, output, and low distortion.
