Single 12-inch rectangular ported subwoofer box with right-side port - 45 L / 32 Hz - 667 × 427 × 312 mm
Description
Designed for a single 12-inch rectangular subwoofer, this vented (bass-reflex) enclosure features a 45 L chamber tuned to 32 Hz. The cabinet is constructed from 18 mm (3/4 inch) material in a simple rectangle shape with external dimensions of 667 × 427 × 312 mm (26.72 × 16.88 × 12.3 in). Optimized for everyday car-audio use, it balances limited trunk space and installation constraints with a coherent sound profile. The design incorporates one L-shaped slot port positioned on the right side for consistent visual alignment and installation. This port area is specifically suited for high-output, large-excursion drivers and SPL-oriented applications requiring high airflow.
