15-inch Round Ported In-Vehicle Subwoofer Box - 85 L / 32 Hz - 685 × 529 × 413 mm

Description

Designed for a single 15-inch round subwoofer, this vented (bass-reflex) enclosure features a 85 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 685 × 529 × 413 mm (27.4 × 20.88 × 16.31 in). A double-thickness front baffle increases rigidity and minimizes panel flex, making it ideal for high-output subwoofer systems. It utilizes one L-shaped slot port with a port area optimized for high-output, large-excursion drivers and SPL-oriented applications with high airflow demand. This versatile design is suitable for everyday car-audio use, accounting for limited trunk space and installation constraints, as well as general-purpose home stereo systems where it balances bass extension, size, output, and low distortion.
