Single 15-inch Round Vented / Bass-Reflex Subwoofer Box - 65 L / 35 Hz

This Vented / Bass-Reflex enclosure is designed for a single 15-inch round subwoofer, featuring a 65 L chamber tuned to 35 Hz. The cabinet is constructed from 18 mm (3/4 inch) material in a simple rectangle shape with external dimensions of 659 × 455 × 355 mm (26.44 × 17.94 × 14.01 in). To ensure high-output performance and reduced panel flex, it incorporates a double-thickness front baffle. This versatile design balances bass extension, size, and low distortion for home music systems, while also considering trunk space and installation constraints for car audio use. It utilizes one L-shaped slot port with a port area optimized for high-excursion drivers and increased airflow demand.
