Single 8-inch Vented / Bass-Reflex Subwoofer Box - 20 L / 38 Hz
Description
Designed for a single 8-inch rectangular subwoofer, this Vented / Bass-Reflex enclosure features a 20 L chamber precision-tuned to 38 Hz. Built from 16 mm (5/8 inch) material in a simple rectangle shape, the cabinet measures 575 × 304 × 243 mm (22.6 × 11.98 × 9.6 in). The double-thickness front baffle increases rigidity and reduces flex, making it ideal for high-output systems. It utilizes one L-shaped slot port with an area optimized for high-airflow SPL use and large-excursion drivers. This design balances bass extension and size for both everyday car audio trunk installs and low-distortion home stereo music systems.
