In-Vehicle Single 8-inch Round Bass-Reflex Subwoofer Box - 25 L / 35 Hz - 595 × 323 × 251 mm

This vented (bass-reflex) enclosure is designed for a single 8-inch round subwoofer and features 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 serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion. The design also accounts for everyday car-audio use, considering limited trunk space, installation constraints, and balanced sound. One L-shaped slot port provides a port area suitable for high-output, large-excursion drivers and SPL-oriented use with high airflow demand.
