Frequent questions about Cento C 165


Welche Materialeigenschaften hat der Cento C 165 Lautsprecher von Hertz?

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 faster response to electrical signals, resulting in a clearer and more detailed sound output, ideal for discerning audio enthusiasts.

Welche elektrischen Spezifikationen bietet der Cento C 165 Lautsprecher?

The Cento C 165 offers a nominal power handling (RMS) of 70 watts and a peak power handling of 210 watts, which means that 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, which ensures 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.

Wie wirkt sich der Neodym-Magnet im Cento C 165 auf die Klangqualität aus?

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, resulting in clearer sound reproduction. This keeps the sound free of distortion even at high levels, providing an excellent acoustic experience, especially for music with a high dynamic range or complex sound structures.

Welche Thiele-Small-Parameter kennzeichnen den 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 magnet system, while a high SPL of 93 dB ensures high efficiency in sound reproduction. These parameters are crucial for individual enclosure adaptation and performance.

Welche Kompatibilität bietet der Cento C 165 mit gängigen Automodellen?

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 automobile manufacturers. As a result, the speaker is universally applicable in common models such as Volkswagen, Audi, BMW, and Mercedes. However, it is still recommended to check the specific vehicle dimensions before installation to ensure that there is enough space available.

Welche Montagetipps gibt es für den Cento C 165 im Auto?

When installing the Cento C 165 speaker in the car, attention must be paid to the installation depth of 62.5 mm and the installation diameter of 142 mm. As a preparatory step, existing door panels should be removed to facilitate access to the speaker openings. Proper screwing 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 cables correctly to avoid phase issues. Additionally, optional speaker grilles can protect the speakers and be aesthetically integrated.

Wie beeinflusst die Schwingspule des Cento C 165 den Klang?

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 a clear, distortion-free sound, ideal for dynamic music or demanding audio applications.

Wie beeinflusst die Frequenzgangcharakteristik des Cento C 165 die Musikqualität?

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, which are important for the clarity of voices and instruments. A wide frequency range means that the speaker is capable of reproducing 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-fledged soundstage with natural transitions between the bass and midrange.

Was sind die physikalischen Konstruktionsmerkmale des Cento C 165 Lautsprechers?

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 the interior of a vehicle.

Welche Langzeitleistung kann man vom Cento C 165 erwarten?

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 loss of performance. 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 particularly 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, especially beneficial for daily commuters or long-distance drivers.
