Hertz CS300S4 – CENTO 12IN 300MM 700W SUBWOOFER 4 OHM
The new CS300S4 Cento subwoofer is the perfect enhancement to every sound system! Powerful bass frequencies from ultra-compact sealed enclosures, optimizing all the electroacoustic parameters according to the target set. The 4 ohm single voice coil configuration offers maximum compatibility with any type of amplification and an enclosure that houses more than one subwoofer. The reduced depth, the compact magnetic group and the lack of rear decompression hole allow the box to be shaped around the subwoofer obtaining a depth close to the one of a speaker for maximum freedom of installation on any type of car. The optional CG 300 grille in robust black metal mesh provide total protection for the subwoofer and an appealing look thanks to the Hertz diamond aluminium logo for better integration into the car.
1. Electroacoustic design optimized for enclosures starting from 32 liters.
2. Fluid dynamic optimization system that drastically reduces the acoustic distortions generated by the air compression at high excursions.
3. Polypropylene cone and dust cap geometry engineered through FEM simulations for low frequency distortion reduction.
4. 35 mm 4 Ω voice coil wound on six layers of pure copper on a high thermal resistance glass fiber support.
5. Magnetic group geometry optimized with proprietary software for high undistorted SPL at high excursions.
6. Ideal for use in custom boxes that can be shaped around the subwoofer thanks to its compact size and lack of the decompression hole.
7. Terminal block featuring solid push contacts that accept cables up to 8 AWG to offer low wiring resistance and maximum ease of connection even in installations with multiple subwoofers.
8. Rubber protection of the magnetic assembly and high-strength ABS plastic gasket allowing the application of the optional grille for an elegant finish.
