Measuring just 305mm x 305mm x 305mm (12.0in x 12.0in x 12.0in) and weighing just 8kg (17.6lb), the partner sub for the ID14 uses a highly efficient bass reflex design employing an 8-inch long-throw neodymium driver. The installation version is available in black, white or custom colors on demand. Connectivity is via two-core shielded cable glands and cables, ensuring IP54 protection, while the front grille is covered by acoustic fabric.
