Dual 12-inch Rectangular Ported In-Vehicle Subwoofer Box - 70L / 35Hz - 954 × 398 × 398 mm

18 Car sub

Description

This Vented / Bass-Reflex enclosure is specifically designed for a 2-driver 12-inch subwoofer setup. Built from 18 mm (3/4 inch) material in a Simple Rectangle shape, the cabinet features external dimensions of 954 × 398 × 398 mm (38.3 × 15.69 × 15.69 in). This design utilizes a 70 L chamber tuned to 35 Hz and incorporates one L-shaped slot port. The port area is optimized for high-output, large-excursion drivers and SPL-oriented applications requiring high airflow. Whether used in a car-audio environment where trunk space and installation constraints are key, or as a general-purpose home subwoofer for music and stereo systems, it perfectly balances bass extension, cabinet size, output, and low distortion.
