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

This Vented / Bass-Reflex enclosure is specifically designed for a dual 15-inch subwoofer configuration. Built from 18 mm (3/4 inch) material in a simple rectangle shape, it features external dimensions of 1134 × 429 × 429 mm (45.35 × 16.92 × 16.92 in). The design includes a 130 L chamber precision-tuned to 30 Hz using a single L-shaped slot port. To ensure suitability for high-output systems and reduce front-panel flex, the cabinet is reinforced with a double-thickness front baffle. The L-shaped slot port area is optimized for high-airflow demand, accommodating large-excursion drivers and SPL applications. Whether used as a general-purpose home subwoofer for music and stereo systems or in everyday car-audio setups, this box balances bass extension, output, and low distortion while respecting trunk space and installation constraints.
