In-Vehicle 12-inch Round Dual-Driver Ported Subwoofer Box - 60 L / 35 Hz - 828 × 364 × 364 mm

This simple rectangle cabinet is built from 18 mm (3/4 inch) material and is designed for a 2-driver 12-inch round subwoofer. Using a Vented / Bass-Reflex design, it features a 60 L chamber tuned to 35 Hz with one L-shaped slot port. The port area is specifically suitable for high-output, large-excursion drivers and SPL-oriented use with high airflow demand. The external dimensions are 828 × 364 × 364 mm (32.61 × 14.34 × 14.34 in). This enclosure works as a general-purpose home subwoofer for music and stereo systems, balancing bass extension, cabinet size, output, and low distortion, while also being optimized for everyday car-audio use by taking limited trunk space, installation constraints, and balanced sound into account.
