Single 12-inch rectangular Vented / Bass-Reflex Subwoofer Box - 45 L / 32 Hz

This Vented / Bass-Reflex enclosure is designed for a single 12-inch rectangular subwoofer, featuring a 45 L chamber tuned to 32 Hz. Constructed from 16 mm (5/8 inch) material in a simple rectangle shape, the external dimensions are 587 × 371 × 333 mm (23.09 × 14.61 × 13.15 in). One internal brace reinforces the cabinet and reduces panel vibration, making it suitable for high-output systems. The design uses one L-shaped slot port with a port area optimized for high-output drivers with increased cone excursion and airflow demand. This versatile box is ideal for everyday car-audio use with limited trunk space or as a general-purpose home subwoofer for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion.
