12-inch Single Round Vented Automotive Subwoofer Box - 30 L / 38 Hz - 563 × 324 × 251 mm
Description
This vented (bass-reflex) enclosure is expertly designed for a single 12-inch round subwoofer, featuring a 30 L chamber tuned to 38 Hz. Constructed from 16 mm (5/8 inch) material in a simple rectangle shape, the external cabinet dimensions are 563 × 324 × 251 mm (22.15 × 12.76 × 9.91 in). It serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion. It is also suitable for everyday car-audio use, accounting for limited trunk space, installation constraints, and balanced sound. The design incorporates one L-shaped slot port with a port area ideal for drivers with moderate cone excursion and airflow demand.
