Hertz CX100 – CENTO 4IN 120W 2-WAY COAXIAL SYSTEM
Coaxial loudspeakers pose a major design challenge due to the critical nature of their acoustic output, being installed in an OEM placement often unfavorable to reproduction. In order to achieve high performance, a great engineering effort was put into place, promptly addressed by our R&D team. The Cento two-way coaxials CX100 features the new 24-millimetre Tetolon dome tweeter that delivers a more musical and detailed sound compared to the more traditional plastic materials. With dispersion optimised for off-axis listening, the SPP-M cone (Semi Pressed Paper-Mica) has been added to ensure superior acoustic and damping characteristics.
Features
- Soft Tetolon fiber 24mm dome tweeter cooled with ferrofluid, for extended and natural high frequencies.
- Rotary High Frequency Contour tweeter angled and directable to the listener for a perfect frequency response in any installation scenario.
- Tweeter faceplate geometry optimised with FEM simulations, to provide an extremely linear frequency response in off-axis installations.
- 4.25mm woofer voice coil featuring an aluminum former to guarantee high excursion and power handling.
- 100mm semi-pressed paper cone SPP-M (Semi Pressed Paper-Mica) enhanced with Mica powder for an excellent balance between lightness and damping.
- High-density flux ferrite magnet combined with low-carbon polar plates for reduced distortion at high power levels.
- Compact and transparent three-spoke basket acoustically combined with a rubber magnet cover for total damping of spurious vibrations.
- Optional elegant grille made with high-resistance ABS plastic structure with a metallic finish combined with a protective metal mesh.
