Description

This vented (bass-reflex) enclosure is designed for a single 15-inch rectangular subwoofer, featuring an 85 L chamber tuned to 32 Hz. The cabinet is constructed from 24 mm (1 inch) material with external dimensions of 700 × 500 × 450 mm (28.01 × 19.72 × 17.75 in). It utilizes one L-shaped slot port with a port area optimized for high-output, large-excursion drivers and high-airflow SPL applications. One internal brace reinforces the cabinet and reduces panel vibration, making it suitable for high-output systems. This design serves as a general-purpose home subwoofer for music and stereo systems, balancing bass extension, size, and low distortion, while also being tailored for everyday car-audio use by considering limited trunk space, installation constraints, and balanced sound.
