Automotive 2-Driver 8-inch Round Bass-Reflex Subwoofer Box - 40 L / 38 Hz - 696 × 327 × 327 mm
Description
This vented (bass-reflex) enclosure is designed specifically for 2-driver 8-inch round subwoofer systems, utilizing 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 696 × 327 × 327 mm (27.37 × 12.88 × 12.88 in). A double-thickness front baffle increases rigidity and reduces flex, making it suitable for high-output setups. It features one L-shaped slot port with an area optimized for large-excursion drivers and high-airflow SPL demands. Whether used as a general-purpose home subwoofer for music or for everyday car audio, the design balances bass extension, output, and low distortion while respecting installation constraints and limited trunk space.
