Frequently Asked Questions about Cento C 165

What material properties does the Cento C 165 Speaker from Hertz have?

The Cento C 165 Speaker uses an SPP-M (Semi Pressed Paper-Mica) material that offers an excellent balance of lightness and stiffness. This diaphragm combines semi-pressed paper with mica powder, resulting in a particularly rigid structure that allows for simultaneous damping and control of the vibration behavior. This creates a particularly natural sound that minimizes unwanted resonances. The use of mica additionally increases stiffness, while the lower weight allows for a quicker response to electrical signals, resulting in a clearer and more detailed sound output, ideal for discerning audio enthusiasts.

What electrical specifications does the Cento C 165 Speaker offer?

The Cento C 165 has a nominal power handling (RMS) of 70 watts and a peak power handling of 210 watts, meaning the speaker can produce powerful sounds even at high volumes. The impedance is 4 ohms, allowing for efficient power distribution. The voice coil has a diameter of 25 mm, wound on an aluminum former, ensuring high excursions and load capacities. The frequency response ranges from 55 Hz to 7 kHz, allowing for a wide sound representation, while a high SPL value of 93 dB ensures sensitive volume levels.

How does the neodymium magnet in the Cento C 165 affect sound quality?

The Cento C 165 uses an extremely strong neodymium magnet in combination with low-carbon pole plates. This configuration reduces distortion, especially at high volumes, by increasing magnetic density while ensuring an even magnetic field distribution. The strong magnet ensures that the voice coil is moved with precise control, leading to clearer sound reproduction. This keeps the sound distortion-free even at high levels and provides an excellent acoustic experience, especially for music with a high dynamic range or complex sound structures.

What Thiele-Small parameters characterize the Cento C 165?

The Cento C 165 Speaker has a Qts value of 0.59, indicating a balanced response in both sealed and bass reflex enclosures. The Vas value is 13.24 liters, which influences the tunable enclosure size for optimal bass reproduction. The Mms value is 13.9 g, indicating a lightweight diaphragm structure that allows for quick responses to electrical signals. The BL value of 4.9 T*m reflects the strength of the magnetic system, while a high SPL of 93 dB ensures high efficiency in sound reproduction. These parameters are crucial for individual enclosure customization and performance.

What compatibility does the Cento C 165 offer with common car models?

The Cento C 165 is a 165 mm (6.5 inch) Speaker that can be easily installed in many vehicles due to its standardized size. The installation requires a mounting depth of 62.5 mm and a mounting diameter of 142 mm. These dimensions are typical for many vehicle doors and comply with the standard specifications of various automotive manufacturers. This makes the speaker universally applicable in common models such as Volkswagen, Audi, BMW, and Mercedes. However, it is recommended to check the specific vehicle dimensions before installation to ensure that there is enough space available.

What installation tips are there for the Cento C 165 in the car?

When installing the Cento C 165 Speaker in the car, attention to the mounting depth of 62.5 mm and the mounting diameter of 142 mm is required. Preparatory steps should include removing existing door panels to facilitate access to the speaker openings. Proper fastening is important to minimize vibrations. Rubber seals as vibration protection around the inside of the basket can prevent unwanted resonances. Make sure to connect the polarity of the wires correctly to avoid phase issues. Additionally, optional Speaker Grilles can protect the speakers and be aesthetically integrated.

How does the voice coil of the Cento C 165 affect the sound?

The 25 mm voice coil of the Cento C 165 is wound on an aluminum carrier, which is essential for high thermal load capacity and excellent sound reproduction at intensity levels. Aluminum provides excellent heat dissipation, allowing the speaker to operate at high power for extended periods without overheating. A precise voice coil ensures that the speaker can drive membranes with high linear movement and low distortion. This results in clear, distortion-free sound, ideal for dynamic music or demanding audio applications.

How does the frequency response characteristic of the Cento C 165 affect music quality?

The Cento C 165 has a frequency response of 55 Hz to 7 kHz, allowing for a comprehensive sound representation. This frequency range includes both deep bass tones and mid frequencies that are important for the clarity of voices and instruments. A wide frequency range means that the speaker can reproduce a variety of audio content with precision and depth, without the need for external equalization. This is particularly beneficial for music lovers who desire a full soundstage with natural transitions between the low and mid-range frequencies.

What are the physical construction features of the Cento C 165 speaker?

The Cento C 165 features a compact 3-spoke basket that effectively suppresses vibrations acoustically through its structural layers. This basket is additionally equipped with a rubber protection to stabilize the magnet and minimize mechanical noise. The speaker weighs 0.96 kg and is 165 mm in size, making it easier to install in various vehicle types. Furthermore, an outer stylish Speaker Grille made of metal and framed in a sturdy plastic frame not only provides protection but can also meet aesthetic demands in a vehicle's interior.

What long-term performance can be expected from the Cento C 165?

With an RMS power handling of 70 watts and a peak power of 210 watts, the Cento C 165 is designed for long operating times without power loss. The use of stable yet lightweight materials like SPP-M reduces the strain on the voice coil, while the efficient magnetic drive design continuously delivers consistent performance at maximum volume. This is especially important when the speaker is used in applications that require high levels during long listening sessions. Its materials and design ensure that sound quality remains consistent even after prolonged use, particularly beneficial for daily commuters or long-distance drivers.
