Single 15-inch Vented / Bass-Reflex Subwoofer Box - 85 L / 32 Hz

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 with a simple rectangle shape, its external dimensions are 700 × 500 × 450 mm (28.01 × 19.72 × 17.75 in). One internal brace reinforces the cabinet and reduces panel vibration, making it suitable for high-output systems. The design utilizes one L-shaped slot port with a port area optimized for high-output, large-excursion drivers and SPL-oriented use with high airflow demand. It serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, size, output, and low distortion, while also being suitable for everyday car-audio use where trunk space and installation constraints are considered for balanced sound.
