Description
Designed for a single 8-inch subwoofer, this Vented / Bass-Reflex enclosure features a 25 L chamber tuned to 35 Hz. The simple rectangle cabinet is built from 16 mm (5/8 inch) material with external dimensions of 563 × 302 × 272 mm (22.12 × 11.9 × 10.71 in). It includes one internal brace to reinforce the panels and reduce vibration, making it suitable for high-output systems. The design utilizes one L-shaped slot port with an area optimized for high-airflow demand and large-excursion drivers in SPL-oriented applications. This versatile box balances bass extension, size, and low distortion for general-purpose home stereo use while remaining compact enough for everyday car-audio installations with limited trunk space.
