Description

This Vented / Bass-Reflex enclosure is specifically designed for 2-driver 12-inch round subwoofer units, featuring a 70 L chamber tuned to 35 Hz. Built from 18 mm (3/4 inch) material in a simple rectangle shape, it uses a double-thickness front baffle to increase rigidity and reduce flex for high-output systems. The external dimensions are 1018 × 398 × 398 mm (40.51 × 15.69 × 15.69 in). This design incorporates a single L-shaped slot port with a port area optimized for large-excursion drivers and high-airflow SPL use. It serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension and low distortion, while also being suitable for daily car-audio use where trunk space and installation constraints are considered.
