12-inch Rectangular Bass-Reflex In-Vehicle Subwoofer Box - 35 L / 35 Hz - 586 × 388 × 349 mm

This Vented / Bass-Reflex enclosure is designed for a single 12-inch rectangular subwoofer, featuring a 35 L chamber tuned to 35 Hz. Built from 16 mm (5/8 inch) material with external dimensions of 586 × 388 × 349 mm (23.06 × 15.28 × 13.75 in), the simple rectangle cabinet includes one internal brace to reduce panel vibration and reinforce the system for high-output use. The design utilizes one L-shaped slot port with an area suitable for high-output, large-excursion drivers and SPL-oriented applications with high airflow demands. It serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, size, and low distortion, while also being optimized for everyday car-audio use where trunk space and installation constraints are key.
