Hertz Cento CK 165 L Datasheet

Frequently Asked Questions about Cento CK 165 L


How does the Tetolon membrane of the Hertz Cento CK 165 L affect sound quality?

The 26 mm Tetolon membrane of the Hertz Cento CK 165 L Tweeter significantly contributes to sound quality by enabling natural and detailed music reproduction in the high-mid frequency range. The 20 mm voice coil complements this by providing precise control under high load. The extremely strong neodymium magnet supports the membrane and ensures that distortion is minimized even at high volumes. This optimized combination guarantees linear frequency reproduction, even in off-axis installations, and offers a wide soundstage that highlights the finest musical nuances. This technology is particularly beneficial if you enjoy listening to music at high volumes.

What technical features does the woofer of the Cento CK 165 L have?

The woofer of the Cento CK 165 L is equipped with a 165 mm non-pressed paper membrane, allowing for a natural sound when reproducing low frequencies. With a 25 mm voice coil on an aluminum former, this component is designed to ensure high excursion and load capacity. The extremely strong neodymium magnet combined with low-carbon pole plates minimizes distortion at high volume. The compact three-spoke basket provides improved vibration damping through its rubber protection. This design ensures that the woofer delivers consistent performance even at elevated levels.

How are the crossovers of the Cento CK 165 L designed?

The crossovers of the Cento CK 165 L consist of separate, ultra-compact modules for the mid-woofer and tweeter. These offer flexible and easy installation. The crossover slope features a low-pass of 6 dB/oct. at 3.8 kHz and a high-pass of 12 dB/oct. at 3.8 kHz. With low-loss components and internal resistances, as well as coils made of pure copper, they provide optimal sound quality. The high-frequency level is adjustable in three positions (-2, 0, +2 dB), ideal for individual adjustment to personal listening preferences, ensuring an optimal balance between highs and lows.

What is the size and load capacity of the Hertz Cento CK 165 L?

The Hertz Cento CK 165 L features a size of 165 mm for the woofer. It is designed for a power handling of 100 Watts RMS and 300 Watts Peak. This combination gives the system the necessary power to deliver full performance even with demanding music pieces. The impedance is 4 Ohms, allowing for compatible integration into many existing vehicle speaker systems. With a sensitivity of 91 dB for woofers, an impressive performance representation is achieved even at lower volumes. This makes it an excellent choice for many car audio enthusiasts.

What frequency response parameters does the Hertz Cento CK 165 L offer?

The frequency response of the Hertz Cento CK 165 L spans a range from 50 Hz to 22.5 kHz. This indicates its ability to cover a wide audio range - from deep bass hits to the sharpest highs. This bandwidth allows for detailed sound reproduction across all music genres. The sensitivity is 92 dB SPL for tweeters and 91 dB SPL for woofers, meaning that even subtle sounds are reproduced accurately and without loss. Such specifications are crucial for listeners who want to experience the nuances and dynamics of a music piece.

What tips are there for installing the Cento CK 165 L in the car?

When installing the Cento CK 165 L in the car, you should first consider the dimensions. The woofer has a diameter of 165 mm and fits into most standard speaker cutouts. The crossover modules are ultra-compact and can be easily installed in most vehicles. Included accessories facilitate adaptation to original installation locations, and the mounting with the stylish Speaker Grille not only provides protection but also an appealing look. Low connection losses and the compact design promote smooth integration and maximum sound fidelity.

How do the voice coils affect the sound performance of the Hertz Cento CK 165 L?

The voice coils of the Hertz Cento CK 165 L are crucial for the sound quality of the system. The tweeters use a 20 mm voice coil, while the woofers are designed with a 25 mm coil to allow for high movements. The use of aluminum carriers for the voice coils optimizes performance by effectively dissipating heat and withstanding mechanical stresses. This design results in consistent transmission performance, even at high volumes, while also providing fine control over dynamic ranges. These features are essential for high-quality car audio setups.

What materials are used in the Cento CK 165 L Speakers?

The Tweeter of the Cento CK 165 L is equipped with a 26 mm Tetolon diaphragm, known for its reproduction accuracy and sound transparency. The woofer uses a Non-Pressed Paper diaphragm (NPP), selected for its lightness and good Damping to represent deep frequencies with a natural sound profile. Neodymium magnets have been used for both speaker types, providing the necessary stability and efficiency to minimize distortion at high volumes. Such high-quality materials significantly contribute to the exceptional sound quality of the speaker system.

What electromechanical parameters affect the Hertz Cento CK 165 L Speakers?

In the Hertz Cento CK 165 L, the electromechanical parameters such as Re at 3.2 Ohms and Le at 0.23 mH are crucial for the impedance and inductance of the driver coils. A Vas value of 13.66 liters with a BL of 4.9 T*m influences the quality and frequency response of the speaker. These values demonstrate the speakers' ability to operate with minimal Damping losses and high control precision. Additionally, the lower Mms value of 14.2 g leads to faster responsiveness to transient signals and improves sound fidelity. Such parameters are fundamental to the performance of the HiFi system.

How does the crossover technology affect the Hertz Cento CK 165 L Speakers?

The crossover technology of the Hertz Cento CK 165 L uses a passive 2-way crossover design that optimizes the frequency response at 3.8 kHz with a low-pass filter slope of 6 dB/Octave and a high-pass of 12 dB/Octave. This technology ensures a clear separation between the tweeter and woofer, resulting in a harmonious audiophile experience and balanced sound. The ability to adjust the treble level in three stages offers flexibility to tailor the listening experience to individual needs. The components used with low losses further contribute to an uninterrupted music enjoyment.
