Single 12-inch Rectangular Vented / Bass-Reflex Subwoofer Box - 40 L / 35 Hz

This Vented / Bass-Reflex enclosure is specifically designed for a single 12-inch rectangular subwoofer, featuring a 40 L chamber tuned to 35 Hz. Built from 16 mm (5/8 inch) material in a simple rectangle shape, the cabinet measures 726 × 417 × 285 mm (28.54 × 16.43 × 11.24 in). It features a double-thickness front baffle to increase rigidity and reduce flex, making it ideal for high-output systems. The design utilizes one L-shaped slot port with an area optimized for high-output, large-excursion drivers and SPL-oriented demands. It serves as a balanced home subwoofer for music and stereo systems, optimizing size and distortion, while its compact footprint is also perfect for everyday car-audio use where trunk space and installation constraints are key.
