Dual 12-inch Round Ported Car Subwoofer Box - 70 L / 35 Hz - 881 × 370 × 370 mm

Designed for a pair of 12-inch round subwoofers, this 70 L Vented / Bass-Reflex enclosure is tuned to 35 Hz to provide a balance of bass extension, output, and low distortion for home stereo systems and music. The simple rectangular cabinet is constructed from 18 mm (3/4 inch) material with external dimensions of 881 × 370 × 370 mm (35.34 × 14.58 × 14.58 in). To handle high-output drivers and minimize front-panel flex, the box features a double-thickness front baffle that increases overall rigidity. It includes one L-shaped slot port with a surface area optimized for high-excursion SPL use and high airflow demand. This design is also well-suited for everyday car-audio applications, carefully considering installation constraints, trunk space, and balanced sound quality.
