The Hertz CS200-S4 Cento subwoofer is a compact passive driver engineered to deliver powerful low frequencies from small sealed enclosures. It is optimized for enclosures starting at 9.6 liters, features a reduced mounting depth and a compact magnetic assembly that allows the box to be shaped around the driver for flexible installation in many vehicle layouts.

Build details include a polypropylene cone and dust cap shaped via FEM simulations, a 35 mm voice coil wound in six layers of pure copper on a glass fiber former, a dedicated cooling system for the voice coil, and a spider designed as an air duct to reduce turbulence and acoustic distortion. The terminal block uses solid push connectors that accept up to 8 AWG cable and an ABS gasket permits fitment of the optional protective grille.
