Dual 8-inch round Vented / Bass-Reflex Subwoofer Box - 50 L / 34 Hz

Description

Designed for a pair of 8-inch round subwoofer drivers, this Vented / Bass-Reflex enclosure features a 50 L chamber tuned to 34 Hz. The cabinet is constructed from 16 mm (5/8 inch) material in a simple rectangle shape with external dimensions of 708 × 328 × 328 mm (27.83 × 12.94 × 12.94 in). A double-thickness front baffle increases rigidity and reduces panel flex, making it suitable for high-output systems. The design utilizes one L-shaped slot port with an area optimized for high-excursion drivers and SPL-oriented use requiring high airflow. This versatile box is engineered for everyday car audio use—considering trunk constraints and balanced sound—as well as home stereo applications where it balances bass extension, size, and low distortion.
