In-Vehicle 2-Driver 12-inch Rectangular Ported Subwoofer Box - 70 L / 35 Hz - 975 × 396 × 396 mm

Description

This Vented / Bass-Reflex enclosure is designed for 2-driver 12-inch rectangular subwoofers, featuring a 70 L chamber tuned to 35 Hz. Built from 16 mm (5/8 inch) material with external dimensions of 975 × 396 × 396 mm (38.32 × 15.6 × 15.6 in), it utilizes a double-thickness front baffle to increase rigidity and reduce panel flex for high-output systems. The design incorporates one L-shaped slot port with an area optimized for high-airflow SPL applications and large-excursion drivers. This simple rectangle cabinet functions as a general-purpose home subwoofer enclosure for music and stereo systems, balancing bass extension, size, and low distortion. It is also engineered for daily car-audio use, accounting for limited trunk space and installation constraints to deliver a balanced sound.
