Description

Designed for a single 15-inch rectangular subwoofer, this Vented / Bass-Reflex enclosure features an 85 L chamber tuned to 32 Hz. The simple rectangular cabinet is constructed from 16 mm (5/8 inch) material with external dimensions of 656 × 495 × 445 mm (25.82 × 19.51 × 17.56 in). It features a double-thickness front baffle and one internal brace to increase rigidity and reduce panel vibration, making it ideal for high-output systems. This versatile design is suitable for everyday car audio use, balancing trunk space and installation constraints with balanced sound, and functions as a general-purpose home subwoofer enclosure that balances bass extension, size, and low distortion. One L-shaped slot port provides a port area suitable for high-output, large-excursion drivers and SPL applications with high airflow demand.
