Description

This Vented / Bass-Reflex enclosure is designed for a single 12-inch rectangular subwoofer and built from 16 mm (5/8 inch) material with a simple rectangle shape. The cabinet features a 40 L chamber tuned to 33 Hz and utilizes one L-shaped slot port with an area suitable for high-output, large-excursion drivers and SPL-oriented use with high airflow demand. Its double-thickness front baffle and one internal brace increase rigidity and reduce panel vibration, making it ideal for high-output subwoofer systems. With external dimensions of 618 × 399 × 359 mm (24.29 × 15.72 × 14.15 in), the design is perfect for everyday car-audio use where trunk space and installation constraints are important, as well as for general-purpose home stereo systems seeking a balance of bass extension, size, and low distortion.
