Description

This 25 L Sealed / Closed-Box enclosure is designed for a single 12-inch round subwoofer. The cabinet features a Simple Rectangle shape constructed from 18 mm (3/4 inch) material, with external dimensions of 417 × 343 × 249 mm (16.77 × 13.52 × 9.81 in). This design serves as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, size, output, and low distortion. Additionally, it is optimized for everyday car-audio use, accounting for limited trunk space, installation constraints, and balanced sound.
