Single 8-inch Rectangular Vented / Bass-Reflex Subwoofer Box - 20 L / 38 Hz
Description
This Vented / Bass-Reflex enclosure is designed for a single 8-inch rectangular subwoofer, balancing bass extension, cabinet size, output, and low distortion for both music systems and everyday car-audio use. Built from 18 mm (3/4 inch) material in a simple rectangle shape, the external dimensions are 560 × 305 × 244 mm (22.55 × 12.07 × 9.63 in). The design features a 20 L chamber tuned to 38 Hz and utilizes one L-shaped slot port. The port area is specifically suited for high-output, large-excursion drivers and SPL-oriented applications with high airflow demand, all while considering limited trunk space and installation constraints.
