The Hertz Cento CX 100 4-inch two-way coaxial speakers are engineered to overcome one of the toughest challenges in car audio: delivering high-quality sound from factory speaker locations that are often acoustically compromised. With this in mind, the Hertz R&D team invested significant effort into optimizing the CX 100 for real-world OEM placements—ensuring outstanding performance where it matters most.

The system features a 24mm Tetolon dome tweeter, chosen for its lightness, damping, and superior musicality over conventional plastic dome materials. This high-performance tweeter provides exceptional clarity and a smooth, detailed high-frequency response, with dispersion specifically tailored for off-axis listening, a critical advantage in automotive environments.

For the midbass, the CX 100 employs a SPP-M (Semi-Pressed Paper-Mica) cone, a material selected for its ideal balance of rigidity and internal damping. This results in natural midrange reproduction, tight midbass, and enhanced acoustic control, even in less-than-ideal enclosures.
