Frequently Asked Questions about Cento CS 200 S4

What are the specifications of the Cento CS 200 S4 Subwoofer?

The Cento CS 200 S4 Subwoofer from Hertz impresses with an RMS power handling of 150 watts and a peak power handling of 300 watts. With a sound pressure level of 84 dB at 1 watt/m, it can produce powerful bass frequencies. The Subwoofer features a single voice coil with a diameter of 35 mm and an impedance of 4 ohms. The maximum excursion is 9 mm, while the mechanical excursion (Xmech) reaches 11.5 mm. The resonance frequency is at 40 Hz, and the effective diaphragm diameter is 172 mm. The Subwoofer is designed to deliver optimal performance, especially in compact sealed enclosures.

What materials are used in the Cento CS 200 S4?

The Hertz Cento CS 200 S4 Subwoofer uses high-quality materials to ensure optimal performance and durability. The diaphragm and dust cap are made of polypropylene, which ensures low frequency distortion. The voice coil is wound on a fiberglass former that provides high thermal resistance, and it consists of six layers of pure copper. The magnet is made of high-density flux ferrite and is designed for maximum energy transfer. A rubber protection around the motor and a high-strength ABS plastic gasket add extra protection and stability, especially with the optional grille attachment.

How is the Cento CS 200 S4 installed?

For the installation of the Cento CS 200 S4, it is important to pay attention to the dimensions. The Subwoofer has a mounting depth of 114 mm and a mounting diameter of 180 mm. This allows for easy integration into various vehicle types. The terminal block with solid pressure contacts can accommodate cables up to 8 AWG, ensuring low wiring resistance. Depending on the chosen enclosure type (sealed or reflex), specific panel dimensions must be considered to achieve optimal acoustic results. A 19 mm thick wood is recommended for the enclosure construction, which supports the durability and frequency characteristics of the system.

How does the cooling system affect the performance of the Cento CS 200 S4?

The innovative cooling system of the Hertz Cento CS 200 S4 uses dynamic liquid optimization to reduce the acoustic distortions caused by high excursions. The system promotes airflow around the voice coil and the magnet, which reduces thermal stress and ensures stable performance during intense use. This design prevents thermal overload and ensures that the Subwoofer operates reliably even at high volumes. Reliability and sound quality are significantly improved by this technology, making it ideal for audiophile applications.

Which enclosure is suitable for the Hertz CS 200 S4?

The Hertz Cento CS 200 S4 is flexible for sealed and reflex bass enclosures. An optimal sealed enclosure has a volume of 9.6 liters, while a reflex enclosure should encompass 14.5 liters. The frequency tuning is set at 60 Hz for sealed and 40 Hz for reflex enclosures. The material thickness of the enclosure should be 19 mm to ensure stability. A damping material is recommended in the reflex enclosure to minimize unwanted resonances. These specifications allow for precise reproduction of low frequencies and optimize the performance of the Subwoofer in various automotive environments.

What electro-acoustic specifications does the CS 200 S4 have?

The electro-acoustic specifications of the Hertz Cento CS 200 S4 are designed for high efficiency and undistorted performance. The Qts value is 0.52, the Qes is 0.58, and the Qms is 5, which provides an optimal trade-off between damping and resonance capability. A BL value of 10.6 T*m indicates strong motor strength. The Subwoofer has a Vas capacity of 13.7 liters, describing the volume air mass that moves the cone under spring preload. The Le value (voice coil inductance) of 1.7 mH shows efficiency in magnetic field control. These parameters are crucial for the precise acoustic design of any application environments.

Can the CS 200 S4 Subwoofer be installed in any car?

The Cento CS 200 S4 from Hertz is compatible with various car models, as the reduced installation depths of 114 mm and the compact mounting diameter of 180 mm provide flexibility for many vehicle types. However, the dimensions of the installation space should be considered to ensure an optimal fit. Due to its design without decompression holes, it is particularly adaptable and suitable for custom enclosure designs that can be shaped around the Subwoofer. This allows the Subwoofer to be used in cars with limited space or in complex sound installations.

How does the motor geometry affect the sound quality of the Cento CS 200 S4?

The proprietary optimized motor geometry of the Hertz Cento CS 200 S4 is designed to achieve undistorted and high SPL (Sound Pressure Level) at high excursions. This optimization ensures that the coil operates without unnecessary mechanical losses, which increases the overall sound fidelity and efficiency of the Subwoofer. The precise design of the magnetic field lines improves linearity and reduces distortion even at high volumes. These advanced modifications are particularly interesting for users seeking high acoustic precision and performance in their car audio environment.

What improvements does the polypropylene diaphragm offer in the CS 200 S4?

The polypropylene diaphragm of the Hertz Cento CS 200 S4 is developed through FEM simulations to minimize low-frequency distortion while providing good ductility and stability. This material choice ensures low weight with high stiffness, supporting the dynamic responsiveness and durability of the diaphragm. The geometry of the diaphragm and dust cap contributes to a consistent sound profile and reduces unwanted resonances, making the Subwoofer ideal for high-quality audio applications in vehicles. This design proves essential for audio enthusiast applications to achieve a demanding sound.

How do the pressure contacts facilitate the installation of the Hertz CS 200 S4?

The solid pressure contacts of the Cento CS 200 S4 Subwoofer from Hertz allow for easy connection of speaker cables with a cross-section of up to 8 AWG. This design significantly lowers wiring resistance and promotes a stable connection even in installations with multiple Subwoofers, thereby increasing the overall efficiency of the system. This user-friendliness is particularly advantageous when integrating into a complex audio system. The robust construction of these contacts also ensures a durable installation, making maintenance and upgrades easier should changes or repairs be necessary.
