40 L / 30 Hz Bass-Reflex Home Audio Subwoofer Box for Single Round 10-inch Driver - 431 × 424 × 367 mm

This general-purpose home subwoofer enclosure for music and stereo systems expertly balances bass extension, cabinet size, output, and low distortion. Designed for a single round 10-inch subwoofer, the vented (Bass-Reflex) enclosure features a 40 L chamber tuned to 30 Hz. The down-firing enclosure houses drivers mounted in the bottom panel, allowing the floor or support surface to become part of the acoustic loading and shape the bass dispersion. Built from 16 mm (5/8 inch) material in a simple rectangle shape, the external dimensions are 431 × 424 × 367 mm (16.97 × 16.71 × 14.46 in). The design uses one L-shaped slot port with a port area suitable for high-output drivers with increased cone excursion and airflow demand.
