Hertz Cento CX 570 Datasheet

Frequently Asked Questions about Cento CX 570


What size do the Hertz Cento CX 570 speakers have?

The Hertz Cento CX 570 speakers have an oval size of 5"x7", making them ideal for many standard car speaker enclosures. The dimensions are specifically designed for a width of 221 mm and a height of 75 mm, which is crucial for installation, especially regarding space-friendly design and adaptation to existing interfaces in vehicle radio systems. The depth of 65.5 mm allows for flexible integration without causing space issues. This seamless fit is particularly important in more compact vehicle models, supported by the oval design.

What is special about the tweeter of the Hertz Cento CX 570?

The Hertz Cento CX 570 speakers stand out with their 24mm tweeter made of Tetolon, which is supported by ferrofluid cooling. This diaphragm surpasses conventional materials with excellent detail reproduction of high frequencies. The material Tetolon is known for its acoustic properties, enabling clear and precise sound. Combined with the external simulation of the geometry via FEM, precise reproduction is ensured even in off-axis installations. This significantly enhances the experience of music playback, allowing the listener to perceive nuances and subtleties in sound that are often lost with other speakers.

What is the power handling of the Cento CX 570 speakers?

The power handling of the Hertz Cento CX 570 speakers impresses with an RMS power of 70 watts, while the peak load is at 210 watts. This makes them suitable for use in various acoustic environments and ensures consistent and stable sound reproduction without distortion or loss of performance. Additionally, the 25mm voice coil, mounted on an aluminum carrier, guarantees excellent thermal handling, ensuring good durability at high volumes. This feature is particularly useful for users who regularly listen to demanding music genres that require higher volumes.

What materials are used in the Cento CX 570 Woofer?

The woofer of the Hertz Cento CX 570 consists of a patented SPP-M membrane, an innovative material that combines semi-pressed paper with mica. This material composition offers an excellent balance of low weight and optimal damping, enabling precise and distortion-free sound reproduction. Supported by a high-density ferrite magnet and low-carbon pole plates, distortion is further significantly reduced. The membrane is supported by a 25mm voice coil mounted on an aluminum carrier, providing additional support in terms of stability and sound fidelity. The design focuses on minimizing unwanted resonances to provide the best listening experience.

How does the RHFC system fit with the Hertz Cento CX 570 speakers?

The RHFC (Rotary High Frequency Contour) system is an integral part of the Hertz Cento CX 570 speakers and was designed to perfectly align the tweeter and ensure optimal sound reproduction in off-axis operation. With this rotatable tweeter design, the listener can adjust the sound output according to their listening position, greatly enhancing individual sound enjoyment. This customizability is crucial, as not every vehicle or room offers the same acoustic conditions. Thus, frequency reproduction can be individually optimized to create a clear and detailed sound image, especially in complex acoustic environments.

How heavy are the Cento CX 570 speakers and what does that mean for installation?

A single Hertz Cento CX 570 speaker weighs 1.0 kg, which is a favorable weight class for installation in most vehicle types. This moderate weight balance supports resonance damping and prevents vibrations that are often amplified by heavier speakers. Despite their innovative materials and extensive technical features, the speakers are lightweight and thus easy to handle when installing in tight vehicle environments. This low weight, combined with a compact 4-spoke basket with rubber magnet protection, makes installation straightforward while effectively decoupling vibrations to positively influence sound quality.

What is the impedance of the Hertz Cento CX 570 speakers?

The Hertz Cento CX 570 speakers have a nominal impedance of 4 ohms, ideal for compatibility with various car amplifier systems. This impedance helps maximize power efficiency and minimize distortion while allowing amplifiers to utilize their full capacity without overload. With this standard impedance, they are well-suited for many car audio installations, enabling seamless integration into the vehicle's electronics. The 4-ohm impedance is widely used and gives the user the flexibility to employ various specialized and high-quality amplifiers without compromising sound quality.

What does the frequency response of the Cento CX 570 speakers look like?

The frequency response of the Hertz Cento CX 570 speakers covers the range from 55 Hz to 22 kHz, allowing them to reproduce a wide spectrum of musical tones and accurately render both low and high frequency ranges. This ensures that all music genres are reproduced faithfully and harmoniously, from deep bass to clear, high notes. The special design of the speakers, including the optimized geometry of the Tweeter faceplate, provides a linear frequency response even in off-axis installations. Thus, these speakers are particularly well-suited to deliver an uncolored, detailed audio experience that emphasizes the true sound of the music.

Are the Hertz Cento CX 570 compatible with vehicles?

The Hertz Cento CX 570 speakers, with their specific 5"x7" oval shape and a depth of 65.5 mm, are generally compatible with many vehicle types that support such speaker sizes. Although no specific car brand is mentioned in the product description, the compact design of these speakers allows for easy fitting into existing mounting locations in a variety of vehicles. However, when planning the installation, it is crucial to consider the specific measurements of the car door panels to ensure that the speakers not only fit but also sound optimal. Integration into the vehicle acoustics can thus occur without significant modifications.

What electromechanical specifications do the Cento CX 570 Loudspeakers offer?

The Hertz Cento CX 570 presents impressive electromechanical properties: a D value of 139 mm, an Re value of 3.3 Ohm, and a resonance frequency (Fs) of 70 Hz. The mechanical loss factor Qms of 3.3 and the electrical loss factor Qes of 0.83 result in a Qts of 0.67. The effective radiating area (Bl factor) is 4.9 T*m, while the magnetic flux is directed through a high-density ferrite magnet. The sound pressure level (SPL) is at 93.5 dB, allowing for high audio performance even at lower amplification. These perfectly balanced parameters ensure a consistently stable and powerful audio sound.
