Single 8-inch Rectangular Vented Car Subwoofer Box - 25 L / 35 Hz - 552 × 284 × 255 mm

Designed for a single 8-inch rectangular subwoofer, this Vented / Bass-Reflex enclosure features a 25 L chamber precision-tuned to 35 Hz. The cabinet is constructed from 16 mm (5/8 inch) material in a Simple Rectangle shape with external dimensions of 552 × 284 × 255 mm (21.7 × 11.19 × 10.07 in). One internal brace reinforces the structure to reduce panel vibration, making it ideal for high-output subwoofer systems. It utilizes one L-shaped slot port with an area specifically suited for high-output drivers with increased cone excursion and airflow demand. Whether used for everyday car audio where trunk space is limited or as a general-purpose home subwoofer for music and stereo systems, this design perfectly balances bass extension, size, output, and low distortion.
