Single 12-inch Vented / Bass-Reflex Subwoofer Box - 35 L / 35 Hz
Description
This Vented / Bass-Reflex enclosure is designed for a single 12-inch round subwoofer, featuring a 35 L chamber professionally tuned to 35 Hz. Built from 16 mm (5/8 inch) material in a simple rectangle shape, the cabinet measures 625 × 368 × 268 mm (24.58 × 14.5 × 10.56 in). It functions as a general-purpose home subwoofer for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion. Additionally, it is optimized for everyday car-audio use by considering limited trunk space, installation constraints, and balanced sound. The design incorporates one L-shaped slot port with an area suitable for high-output drivers requiring increased cone excursion and airflow.
