Single 10-inch Rectangular Vented / Bass-Reflex Subwoofer Box (25 L / 38 Hz)

This simple rectangular cabinet is designed for a single 10-inch rectangular subwoofer, constructed from 16 mm (5/8 inch) material with external dimensions of 600 × 329 × 296 mm (23.58 × 12.96 × 11.67 in). The 25 L chamber is tuned to 38 Hz using a Vented / Bass-Reflex design with one L-shaped slot port. To ensure suitability for high-output subwoofer systems, the enclosure features a double-thickness front baffle and one internal brace to increase rigidity and reduce panel vibration. The L-shaped slot port area is optimized for high-output, large-excursion drivers and SPL-oriented use with high airflow demand. This design serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, size, output, and low distortion, while also being ideal for everyday car-audio use where limited trunk space and installation constraints are important.
