Hertz CX100 Cento Series 4″ 2-Way Coaxial Speaker

Description

Highlights

Coaxial loudspeakers represent a major design challenge due to the critical nature of their acoustic output, being installed in an OEM placement often unfavorable to reproduction. 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 coaxial CX 100 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. 

• 2-Way car speakers
• 2 Year Warranty
• 4″ treated paper woofer with polyurethane surround

(grilles not included)

Features

• Soft Tetolon® fiber 24 mm (0.9 in.) dome tweeter cooled with ferrofluid, for extended and natural high frequencies.
• RHFC ™ (Rotary High Frequency Contour) tweeter angled and direct-able to the listener for a perfect frequency response in any installation scenario.
• Tweeter faceplate geometry optimized with FEM simulations (Finite Element Modeling), to provide an extremely linear frequency response in off-axis installations.
• 25 mm (1 in.) woofer voice coil featuring an aluminum former to guarantee high excursion and power handling.
• 100 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.
• 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.
• Elegant grille made with high-resistance ABS plastic structure with a metallic finish combined with a protective metal mesh, available as optional
