Dual 15-inch Vented / Bass-Reflex Subwoofer Box - 130 L / 30 Hz

This rectangular Vented / Bass-Reflex enclosure is designed for 2-driver 15-inch subwoofers and is built from 18 mm (3/4 inch) material. The 130 L chamber is tuned to 30 Hz using a single L-shaped slot port with an area suitable for high-output drivers with increased cone excursion and airflow demand. The design features a double-thickness front baffle to increase rigidity and reduce flex, making it ideal for high-power systems. With external dimensions of 1070 × 413 × 413 mm (42.79 × 16.27 × 16.27 in), this versatile box balances bass extension and size for home music systems while remaining compact enough for daily car audio use with trunk space constraints.
