Hertz C 165 F
C 165 F165 (6.5) mm (in.) | Woofer | 180 W | 4 Ohm
The installation of after-market woofers in factory placements limited by a reduced depth is a recurring problem that forces specialists to make complicated mechanical changes, extending the time to finish the job significantly. The Cento line new C 165 F flat profile woofer is the solution, thanks to a super slim basket with reduced depth that allows the use even in the most problematic OEM scenarios, widespread in new generation cars. The R&D team, through an extensive design process was able to obtain high performance even with the super slim basket feature. This was made possible by the optimization of the mobile group excursion and the new design of the cone and dustcup geometry. Like the other components of the Cento range, the use of SPP-M (Semi-Pressed Paper-Mica) provides the C 165 F with a light and rigid cone at the same time that guarantees high efficiency and an extended frequency response.
