Hertz 5.25" Coaxial Speaker

For this reason, 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 CX 130 features the new 24 mm (0.9 in.) Tetolon® dome tweeter that delivers a more musical and detailed sound compared to the more traditional plastic materials. The dispersion has been optimized for off-axis listening. The SPP-M cone (Semi Pressed Paper-Mica) ensuring superior acoustic and damping characteristics.

• 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) tweeter angled and directable to the listener for a perfect frequency response in any installation scenario.
• 3. Tweeter faceplate geometry optimized with FEM simulations (Finite Element Modeling), to provide an extremely linear frequency response in off-axis installations.
• 4. 25 mm (1 in.) woofer voice coil featuring an aluminum former to guarantee high excursion and power handling.
• 5. 130 mm (5 in.) semi-pressed paper cone SPP-M (Semi Pressed Paper-Mica) enhanced with Mica powder for an excellent balance between lightness and damping.
• 6. High-density flux ferrite magnet combined with low-carbon polar plates for reduced distortion at high power levels.
• 7. Compact and transparent three-spoke basket acoustically combined with a rubber magnet cover for total damping of spurious vibrations.
• 8. Elegant grille made with high-resistance ABS plastic structure with a metallic finish combined with a protective metal mesh, available as optional.
