Single 12-inch round Vented residential audio subwoofer box - 65 L / 27 Hz - 519 × 430 × 453 mm

16 Double Home sub Down-firing

Description

Designed for a single 12-inch round subwoofer, this general-purpose residential Vented enclosure balances bass extension, cabinet size, output, and low distortion for music and stereo systems. This simple rectangle cabinet is built from 16 mm (5/8 inch) material with external dimensions of 519 × 430 × 453 mm (20.43 × 16.93 × 17.87 in). It features a 65 L chamber tuned to 27 Hz using one round port, with a port area suitable for high-output drivers with increased cone excursion and airflow demand. The down-firing enclosure design mounts the driver in the bottom panel so the floor or support surface becomes part of the acoustic loading and shapes the bass dispersion. A double-thickness front baffle increases cabinet rigidity and reduces front-panel flex, making the box suitable for high-output subwoofer systems.
