Single 15-inch Round Vented / Bass-Reflex Subwoofer Enclosure - 65 L / 35 Hz

This Vented / Bass-Reflex enclosure is designed for a single 15-inch round subwoofer, featuring a 65 L chamber tuned to 35 Hz. Constructed with a simple rectangle shape from 16 mm (5/8 inch) material, it measures 606 × 425 × 383 mm (23.83 × 16.77 × 15.09 in). One internal brace reinforces the cabinet and reduces panel vibration, making the system suitable for high-output subwoofers. Its L-shaped slot port provides an area optimized for high-output drivers with increased cone excursion and airflow demand. This design balances bass extension, cabinet size, and low distortion for everyday car-audio use with limited trunk space or as a general-purpose home subwoofer for music and stereo systems.
