Description

This Vented / Bass-Reflex enclosure is designed for a single 15-inch round subwoofer, featuring a 65 L chamber tuned to 35 Hz. Built from 16 mm (5/8 inch) material in a Simple Rectangle shape, the cabinet measures 618 × 465 × 418 mm (24.3 × 18.31 × 16.48 in). It utilizes one L-shaped slot port with a port area suitable for high-output, large-excursion drivers and SPL-oriented use with high airflow demand. One internal brace reinforces the cabinet and reduces panel vibration, making it suitable for high-output systems. This design is ideal for everyday car-audio use, considering limited trunk space and installation constraints, while also serving as a general-purpose home subwoofer enclosure for music and stereo systems that balances bass extension, size, and low distortion.
