Hertz CX570 – CENTO 5X7IN 2 WAY COAXIAL SYSTEM 210W
Coaxial loudspeakers represent a major design challenge due to their acoustic outputs critical nature. Being installed in an OEM placement often unfavourable to reproduction, our R&D experts made strides to achieve high performance, while promptly addressing the problem. Hence, the Cento two-way coaxials CX570 features the new 24-millimetre (0.9″) Tetolon dome tweeter that delivers a more musical and detailed sound compared to ones made from traditional plastic materials. Plus, the dispersion has been optimised for off-axis listening by adding in the SPP-M cone (Semi Pressed Paper-Mica) that ensures superior acoustic and damping characteristics across the board.
1. Soft Tetolon® fiber 24 mm (0.9 in.) dome tweeter cooled with ferrofluid, for extended and natural high frequencies.
2. RHFC ™ (Rotary High Frequency Contour) directable tweeter for optimal off-axis frequency response and dispersion on the listening point.
3. Adjustable high frequency system for perfect frequency response to any listening point.
4. Tweeter faceplate geometry optimized with FEM simulations (Finite Element Modeling), to provide an extremely linear frequency response in off-axis installations.
5. 25 mm (1 in.) woofer voice coil featuring an aluminum former to guarantee high excursion and power handling.
6. 5×7 in. semi-pressed paper cone SPP-M (Semi Pressed Paper-Mica) enhanced with Mica powder for an excellent balance between lightness and damping.
7. High-density flux ferrite magnet combined with low-carbon polar plates for reduced distortion at high power levels.
8. Compact and transparent four-spoke basket acoustically combined with a rubber magnet cover for total damping of spurious vibrations.
