Description

This Vented / Bass-Reflex enclosure is designed for a single 15-inch rectangular subwoofer, featuring a 65 L chamber tuned to 33 Hz. Constructed from 16 mm (5/8 inch) material with external dimensions of 645 × 473 × 426 mm (25.36 × 18.65 × 16.79 in), the simple rectangular cabinet includes a double-thickness front baffle and one internal brace to increase rigidity and reduce vibration in high-output systems. It utilizes one L-shaped slot port with an area optimized for high-airflow demand and large-excursion SPL drivers. This versatile design serves as a general-purpose home subwoofer for music and stereo systems, balancing extension and low distortion, while also remaining suitable for everyday car-audio use where trunk space and installation constraints are key.
