Frequent questions about Cento Pro CPX 690


Wie ist der Frequenzgang der Cento Pro CPX 690 Lautsprecher?

The frequency response specification of the Cento Pro CPX 690 by Hertz ranges from 35 Hz to 24 kHz. This wide frequency range allows for an impressive sound diversity of the speakers, from deep bass to clear highs. The neodymium magnets of the tweeters and supertweeters support this performance to ensure precise reproduction of high frequencies. Similarly, the use of Tetolon membranes contributes to a balanced and resonance-free sound. Especially when one values a full sound image, these speakers are designed to represent even subtle sound nuances.

Welche Leistung bieten die Cento Pro CPX 690 Lautsprecher in Bezug auf Belastbarkeit?

The Cento Pro CPX 690 speakers from Hertz feature an RMS power handling of 120 watts and achieve a peak power of up to 360 watts. This provides ample reserves for a dynamic sound spectrum, which is particularly advantageous at higher volumes. To better handle high power levels, ferrite magnets combined with low-carbon pole plates have been used to minimize distortion. This construction makes them ideal for intense music listening experiences and ensures that sound quality is maintained even at maximum volume.

Warum sind die Neodym-Magnete der Hochtöner und Supertweeter der CPX 690 so vorteilhaft?

The use of neodymium magnets in the tweeters and supertweeters of the Cento Pro CPX 690 speaker offers several technical advantages. Neodymium is a material with high magnetic density, allowing for smaller and lighter magnets. This leads to more efficient sound conversion and increases the dynamic range of high frequencies. Tetolon membranes complement this by providing clarity and detail fidelity. The design of the tweeters also allows for improved off-axis performance, thanks to their optimized geometry, which is particularly beneficial in demanding installation scenarios.

Welche Abmessungen haben die Cento Pro CPX 690 und wie beeinflusst dies ihre Installation?

The Cento Pro CPX 690 speakers have dimensions of 6" x 9" with specific measurements of 237.5 x 225 mm for their outer diameter. The installation depth is 103 mm and the magnetic depth measures 85 mm. Such dimensions should be considered during installation to ensure that the installation location provides sufficient space, especially regarding the depth behind the mounting bracket. When placing, it is crucial to adhere to the specified geometry to achieve maximum sound quality through optimal fit and to avoid resonance issues.

Wie tragen die Tetolon-Membranen zur Klangqualität der CPX 690 bei?

The Tetolon membranes of the Hertz Cento Pro CPX 690 speakers play a crucial role in the reproduction quality of higher frequencies. Tetolon is a material capable of transmitting sound waves with high precision and is characterized by excellent damping properties. This reduces unwanted vibrations and ensures clean high-frequency reproduction. Together with the neodymium magnet technology, these membranes guarantee a linear frequency response and high sound fidelity, making the speakers particularly recommended for audiophile applications.

Welches Gewicht haben die Cento Pro CPX 690-Lautsprecher und warum ist das relevant?

The Cento Pro CPX 690 speakers have a total weight of 1.63 kg. This weight positively affects the stability of the speakers. A higher weight is often an indicator of the quality of workmanship and the robustness of the materials; here, the ferrite magnet for the woofer and the solid metal basket are particularly noteworthy. This positively influences the sound performance by minimizing unwanted vibrations and contributing to the overall strength of the speaker construction, which in turn allows for clear and undistorted sound reproduction.

Welche Materialien werden im Hertz Cento Pro CPX 690 Lautsprecher verwendet?

The Cento Pro CPX 690 from Hertz utilizes a variety of materials that have been carefully selected to maximize acoustic performance. The membranes are made from water-repellent, pressed paper that provides both stiffness and lightness. Ferrites are used for the bass magnet, while neodymium is employed in the tweeters and super tweeters. This choice allows for high magnetic efficiency with minimized weight. The robust metal basket is additionally equipped with a vibration-damping rubber magnet cover to significantly reduce vibrations and resulting distortions.

Was sind die Vorteile des Radial Venting Systems der CPX 690?

The radial venting system of the Cento Pro CPX 690 speakers is crucial for the cooling performance of these components. This design allows for improved ventilation of the voice coil, which increases thermal resilience and minimizes thermal compression. This feature is particularly important at high power input to enhance the longevity of the speaker. In addition to this structural ventilation, the rubber coating contributes to vibration damping. This innovation from Hertz ensures that the speakers deliver excellent sound even at higher volumes and during prolonged operation.

Wie beeinflussen die Xmech-Technologie und Gummifederung die CPX 690 Leistung?

The Xmech technology of the Cento Pro CPX 690 speakers allows for a maximum mechanical displacement of 7.5 mm. In combination with the wide rubber suspension, this technology ensures that the speaker can produce extremely dynamic bass responses at high volumes without generating distortion. The rubber suspension also improves shock absorption, resulting in cleaner acoustics. This design guarantees that the woofers operate precisely even under demanding conditions, while maintaining the stability of the diaphragm at maximum displacement, which is crucial for bass enthusiasts.

Wie kann die Gehäusekonstruktion der CPX 690 die Klangqualität beeinflussen?

The housing construction of the Cento Pro CPX 690 speakers has a significant impact on sound quality. The metal basket with an integrated vibration-damping rubber cover minimizes disturbing resonances and contributes to a clear sound image. The design with water-repellent membranes ensures consistently high performance without degeneration due to moisture. The combination of a robust ABS plastic frame and a metal surface in the stylish grille not only enhances the appearance but also protects the interior from mechanical influences. This thoughtful construction supports acoustic performance and ensures long-lasting reliability.
