Description

This Vented / Bass-Reflex enclosure is specifically designed for a single 15-inch rectangular subwoofer, featuring a 65 L chamber tuned to 35 Hz. Built from 16 mm (5/8 inch) material with a double-thickness front baffle and one internal brace, the simple rectangle cabinet provides increased rigidity and reduced vibration for high-output systems. The design utilizes one L-shaped slot port with an area optimized for high-airflow demand, large-excursion drivers, and SPL applications. With external dimensions of 639 × 465 × 418 mm (25.14 × 18.31 × 16.48 in), this box is ideal for everyday car audio use where trunk space and installation constraints are factors, as well as home stereo systems seeking a balance between bass extension, cabinet size, and low distortion.
