Single 10-inch Rectangular Vented / Bass-Reflex Subwoofer Box - 30 L / 38 Hz

Designed for a single 10-inch rectangular subwoofer, this Vented / Bass-Reflex enclosure features a 30 L chamber tuned to 38 Hz using one L-shaped slot port. Built from 18 mm (3/4 inch) material in a simple rectangle shape, the external dimensions are 586 × 337 × 303 mm (23.58 × 13.3 × 11.97 in). The port area is specifically suitable for high-output, large-excursion drivers and SPL-oriented use with high airflow demand. One internal brace reinforces the cabinet and reduces panel vibration, making it ideal for high-output subwoofer systems. This design is versatile enough for everyday car-audio use with limited trunk space or as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion.
