    Hertz CS-300-S4 Cento Series 12" Subwoofer

    The new CS 300 s4 Cento subwoofer is the perfect enhancement to every sound system, to fully enjoy the authentic Hertz Sound Experience!
    The R & D team, always at the forefront in the search for innovative solutions, with unfailing effort, succeeded in obtaining very powerful bass frequencies from ultra-compact sealed enclosures, optimizing all the electroacoustic parameters according to the target set: high performance with boxes starting from 32 l. for the 30 cm (12 in.) CS 300 model.
    The 4Ω 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 special cooling system of the six-layer voice coil keeps the operating temperature within an optimal range even in case of extended listening sessions at high acoustic pressure.
    An innovative system of dynamic fluid optimization and turbulence reduction, obtained thanks to the spider support acting as an air conduct towards the venting holes on the basket, drastically reduces the acoustic distortions generated by the air compression at high excursions.
    The cone geometry, the suspension and the spider have been designed using FEM (Finite Element Method) simulations to obtain the best performance configuration that guarantees control and low distortions even at high mechanical excursions of the mobile group.
    The terminal block uses solid push connectors that accept cables up to 8 AWG to offer low wiring resistance and maximum ease of connection even in installations with multiple subwoofers.
    The subwoofer is also provided with an elegant high resistance ABS plastic gasket that allows the grille to be fixed to finish the installation.
    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.
    With the Cento subwoofers even the younger enthusiasts will enjoy an exciting reproduction of low frequencies in the car!


    • Electroacoustic design optimized for enclosures starting from 32 liters.
    • Fluid dynamic optimization system that drastically reduces the acoustic distortions generated by the air compression at high excursions.
    • Polypropylene cone and dust cap geometry engineered through FEM simulations for low frequency distortion reduction.
    • 35 mm 4 Ω voice coil wound on six layers of pure copper on a high thermal resistance glass fiber support.
    • Magnetic group geometry optimized with proprietary software for high undistorted SPL at high excursions.
    • Ideal for use in custom boxes that can be shaped around the subwoofer thanks to its compact size and lack of the decompression hole.
    • 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.
    • Rubber protection of the magnetic assembly and high-strength ABS plastic gasket allowing the application of the optional grille for an elegant finish.

What Our Customers Say About Us

  • After shopping at several places, both on-line and in stores, I had decided to order from a local store that advertised a good price, but found out they were out of stock. ABT had the same price, in stock, with free shipping, and the product arrived on time. The packaging was very good too. Highly recommend!
