Single 15-inch Round Vented / Bass-Reflex Subwoofer Box - 65 L / 32 Hz

This Vented / Bass-Reflex enclosure is specifically designed for a single 15-inch round subwoofer, providing a balanced solution for both high-output car audio and home stereo systems. The simple rectangular cabinet is constructed from 18 mm (3/4 inch) material and features a double-thickness front baffle to increase rigidity and minimize panel flex for high-excursion drivers. With external dimensions of 678 × 512 × 400 mm (27.11 × 20.21 × 15.79 in), the design optimizes limited trunk space while maintaining excellent bass extension. The 65 L chamber is tuned to 32 Hz using one L-shaped slot port. This port area is engineered for high airflow demand, making it ideal for SPL-oriented use and large-excursion subwoofers with low distortion.
