Description

This vented (bass-reflex) enclosure is designed for a single 15-inch round subwoofer, featuring an 85 L chamber tuned to 32 Hz. Constructed from 24 mm (1 inch) material in a simple rectangle shape, the cabinet measures 735 × 500 × 450 mm (29.52 × 19.72 × 17.75 in). A double-thickness front baffle and one internal brace enhance rigidity and minimize vibration, making it ideal for high-output systems. The design incorporates one L-shaped slot port with an area optimized for high-airflow demand and large-excursion drivers in SPL applications. Whether used in a car audio setup with limited trunk space or as a home subwoofer for music and stereo systems, it perfectly balances bass extension, output, and low distortion.
