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

Designed for a single 8-inch round subwoofer, this Vented / Bass-Reflex enclosure features a 25 L chamber tuned to 35 Hz. The cabinet is constructed from 16 mm (5/8 inch) material in a simple rectangle shape with external dimensions of 593 × 302 × 272 mm (23.32 × 11.9 × 10.71 in). To handle high-output systems, it includes a double-thickness front baffle and one internal brace to increase rigidity and reduce panel vibration. The design utilizes one L-shaped slot port with an area optimized for high-output, large-excursion drivers and high airflow SPL demands. This versatile box balances bass extension, size, and low distortion, making it ideal for both space-conscious car audio installations and general-purpose home stereo systems.
