Description
This vented (bass-reflex) enclosure is specifically designed for a single 12-inch rectangular subwoofer, featuring a 40 L chamber tuned to 35 Hz. Built from 16 mm (5/8 inch) material in a simple rectangle shape, the external dimensions are 622 × 409 × 305 mm (24.47 × 16.12 × 12.02 in). It utilizes one L-shaped slot port positioned on the right side to ensure consistent installation and visual alignment. The design balances sound quality with car-audio practicality for everyday use in limited trunk spaces. Furthermore, the port area is optimized for high-output, large-excursion drivers and SPL-oriented applications with high airflow demand.
