The Hertz CS 300 is a 12-inch (300 mm) subwoofer driver from the Hertz Cento range, offered as the CS 300 S2 (single 2-ohm voice coil) or the CS 300 S4 (single 4-ohm voice coil), both rated at 700 W peak and 350 W continuous.
- Electroacoustic design optimised for compact sealed enclosures from 32 litres
- Polypropylene cone and dust cap shaped with FEM simulations to reduce low-frequency distortion
