Description

This Vented / Bass-Reflex enclosure is designed for 2-driver 8-inch round subwoofer units, featuring a 40 L chamber tuned to 38 Hz. The simple rectangle cabinet is built from 16 mm (5/8 inch) material with external dimensions of 652 × 313 × 313 mm (25.63 × 12.32 × 12.32 in). A double-thickness front baffle increases cabinet rigidity and reduces front-panel flex, making it ideal for high-output systems. The design utilizes one L-shaped slot port with a port area suitable for high-output, large-excursion drivers and SPL-oriented use with high airflow demand. Whether used as a general-purpose home subwoofer to balance bass extension and low distortion or for everyday car-audio use with limited trunk space, this enclosure delivers a balanced sound.
