Single 12-inch Rectangular Vented / Bass-Reflex Subwoofer Box - 35 L / 35 Hz
Description
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 in a simple rectangle shape, the cabinet measures 665 × 368 × 268 mm (26.12 × 14.5 × 10.56 in). It includes a double-thickness front baffle to increase rigidity and reduce flex, making it suitable for high-output systems. One L-shaped slot port provides an area optimized for high-output drivers with increased cone excursion and airflow demand. This design serves as a general-purpose home subwoofer for music and stereo systems, balancing bass extension and distortion, while also being ideal for daily car-audio use where trunk space and installation constraints are key.
