In-Vehicle 8-inch Round Single Vented Subwoofer Box - 25 L / 35 Hz - 552 × 284 × 255 mm

This vented (bass-reflex) enclosure is designed for a single 8-inch round subwoofer, featuring a 25 L chamber tuned to 35 Hz with a single L-shaped slot port. The cabinet is built from 16 mm (5/8 inch) material in a simple rectangle shape with external dimensions of 552 × 284 × 255 mm (21.7 × 11.19 × 10.07 in). One internal brace reinforces the cabinet and reduces panel vibration, making it suitable for high-output subwoofer systems. The port area is optimized for high-output drivers with increased cone excursion and airflow demand. This design serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion, while also being ideal for everyday car-audio use where trunk space and installation constraints require balanced sound.
