Description

This vented (bass-reflex) enclosure is designed for a single 15-inch rectangular subwoofer, featuring a 65 L chamber tuned to 33 Hz. Built from 18 mm (3/4 inch) material in a simple rectangle shape, the cabinet measures 639 × 475 × 427 mm (25.51 × 18.75 × 16.87 in). One internal brace reinforces the structure and reduces panel vibration, making it ideal for high-output systems. The design uses one L-shaped slot port with a port area suitable for high-excursion drivers and SPL-oriented use with high airflow demands. It is perfect for everyday car-audio use where trunk space and installation constraints are important, or as a general-purpose home subwoofer that balances bass extension, size, output, and low distortion.
