Single 12-inch Round 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 tuned to 35 Hz. Built from 16 mm (5/8 inch) material in a Simple Rectangle shape, the cabinet measures 720 × 414 × 284 mm (28.28 × 16.3 × 11.2 in). It utilizes one L-shaped slot port with an area suitable for high-output, large-excursion drivers and SPL-oriented use requiring high airflow. The double-thickness front baffle increases rigidity and reduces flex, making it ideal for high-output systems. This versatile design balances bass extension, size, and low distortion for home stereo use, while also considering trunk space and installation constraints for everyday car-audio applications.
