8-inch 2-driver rectangular Bass-Reflex automotive subwoofer box - 40 L / 38 Hz - 696 × 327 × 327 mm

This vented (bass-reflex) enclosure is designed for two 8-inch subwoofer drivers and features a 40 L chamber tuned to 38 Hz. Constructed from 16 mm (5/8 inch) material with a simple rectangle shape, the cabinet measures 696 × 327 × 327 mm (27.37 × 12.88 × 12.88 in). The design includes a double-thickness front baffle to increase rigidity and reduce panel flex, making it ideal for high-output subwoofer systems. It utilizes one L-shaped slot port with a port area optimized for high-output, large-excursion drivers and SPL-oriented use requiring high airflow. Whether used for everyday car audio to balance limited trunk space and installation constraints or as a general-purpose home subwoofer for music and stereo systems, this box perfectly balances bass extension, size, and low distortion.
