Dual 15-inch Round Ported Subwoofer Box for Vehicles - 130 L / 30 Hz - 1134 × 429 × 429 mm

This Vented / Bass-Reflex enclosure is specifically designed for 2-driver 15-inch round subwoofer systems, featuring a 130 L chamber tuned to 30 Hz. Built as a simple rectangle from 18 mm (3/4 inch) material, the cabinet has external dimensions of 1134 × 429 × 429 mm (45.35 × 16.92 × 16.92 in). It includes a double-thickness front baffle to increase rigidity and reduce panel flex, making it ideal for high-output setups. The design incorporates one L-shaped slot port with a surface area suitable for high-excursion drivers and high-airflow SPL applications. This versatile box balances bass extension and low distortion, serving as an excellent general-purpose home subwoofer enclosure for stereo systems or a balanced daily-use car audio solution that respects trunk space and installation constraints.
