Frequently Asked Questions about Cento CK 165

What distinguishes the Cento CK 165 in terms of its frequency response?

The Cento CK 165 from Hertz impresses with a frequency response of 55 Hz to 22.5 kHz, allowing it to cover a wide range of audio signals. The Tweeter C 26, with its 26 mm Tetolon membrane, ensures clear reproduction of highs and mid-highs. Thanks to the passive 2-way Crossover with a cutoff at 2.5 kHz @ 12 dB/octave, sound distribution is optimally coordinated. The impedance of 4 Ohms and the sensitivity of 93 dB SPL contribute to the excellent sound quality and efficiency of the system, ensuring a fine balance between volume level and sound details.

What technical features does the Tweeter of the Cento CK 165 have?

The Tweeter C 26 of the Cento CK 165 features a 26 mm Tetolon membrane and a 20 mm voice coil, which together support detailed and natural sound reproduction. The Tetolon fiber® diaphragm ensures accurate musical reproduction, while the neodymium magnet provides a high-density magnetic flux specifically designed for dynamic transients in the mid to high frequency range. The geometry of the front plate is optimized with FEM technology, allowing for a linear frequency response even in off-axis installations, meaning when the installation angle is not frontal.

What is the power handling of the Cento CK 165 speaker system?

The Cento CK 165 offers outstanding power handling with an RMS power handling of 95 W and a peak power handling of 285 W. These specifications ensure that the speaker system is suitable for both everyday use and more intense audio applications without distortion. The aluminum former of the voice coil in the woofer allows for high excursion, which is particularly advantageous under high power loads. Thus, the system is excellent for use in various acoustic environments where high power input is necessary.

What materials are used in the diaphragm construction of the Cento CK 165?

The diaphragm of the C 165 mid-woofer of the Cento CK 165 system is made from semi-pressed SPP-M paper, enriched with mica powder. This material composition provides an outstanding balance between lightness and damping, resulting in reduced vibrations and clearer sound reproduction. The tweeter uses a Tetolon diaphragm, which ensures precise highs. These high-quality materials contribute to the excellent sound profile of the system by reducing unwanted resonances and increasing sound fidelity, which is particularly noticeable in the reproduction of complex musical pieces.

How does the flux ferrite magnet of the Cento CK 165 affect sound quality?

The flux ferrite magnet in the Cento CK 165 allows for a high density of magnetic flux, which is crucial for minimizing distortion at high power levels. This feature ensures that the speaker delivers clear and undistorted sound even at higher volumes. Combined with low-carbon pole plates, the magnet reduces additional interference and supports the overall sound stability of the system. This technology ensures clear and balanced audio performance across the entire frequency range, which is especially important for audiophile users and discerning listeners.

What are the dimensions and how does the Hertz Cento CK 165 assist with installation in the vehicle?

The Cento CK 165 has a size of 165 mm for the mid-woofer, which corresponds to a common standard size for integration in vehicles. The electro-acoustic specification D is 131.5 mm, and the compact design of the speaker facilitates installation in most vehicle models. The system is equipped with an elegant speaker grille made of high-strength ABS plastic structure, which supports the robustness of the installation. The designed size and included accessories allow for easy integration, fitting into existing mounting frames without extensive modifications.

How is the tweeter level adjustment possible on the Cento CK 165?

The tweeter level of the Cento CK 165 can be adjusted via a three-position switch on the Crossover CCX 2. You can choose between settings of 0 dB and +3 dB to achieve an optimal sound balance. This adjustment option allows the user to tailor the sound to individual listening habits and the acoustic space in the vehicle. By using capacitors with a low loss factor and low-resistance inductors made of pure copper, sound transparency is maximized, ensuring clear audio output, especially at high frequencies.

What role does the voice coil play in the C 165 woofer of the Cento CK 165?

The voice coil of the woofer in the Cento CK 165 has a diameter of 25 mm and is equipped with an aluminum former. This construction allows for high displacement, which is crucial for powerful bass output. The coil provides the necessary mechanical power to efficiently set the diaphragm in motion, thus producing deep and resonance-free bass. This enhances acoustic performance by reducing distortion at high volumes and simultaneously offers durability for different music genres, which is a clear advantage for lovers of lower frequencies.

How does the Crossover technology in the Cento CK 165 affect sound quality?

The Cento CK 165 uses a passive 2-way Crossover that enables the crossover cutoff at 2.5 kHz @ 12 dB/octave. This technology ensures precise allocation of frequencies to the respective speaker types. The use of high-quality components such as low-loss capacitors and low-resistance inductors made of pure copper enhances sound transparency. The Crossover ensures that the Tweeter and woofer are only supplied with the frequencies they can optimally reproduce, minimizing interference and ensuring clear and coherent audio output. As a result, the performance in the car remains high-quality, even with particularly complex music.

What significance does the geometry of the front plate in the C 26 Tweeter have in the Cento CK 165?

The geometry of the front plate in the C 26 Tweeter of the Cento CK 165 has been optimized using FEM technology (Finite Element Modeling). This optimization plays a crucial role in achieving a linear frequency response, especially in off-axis installations, meaning installation situations where the speaker is not directly aimed at the listener. The designed front plate reduces phase anomalies and improves the spatial representation of sound. This technique helps overcome challenges posed by various installation angles and enhances sound quality and fidelity, which is particularly beneficial in vehicles with variable seating arrangements.
