Frequent questions about Cento CX 690


Wie beeinflusst die Membran des Cento CX 690 die Soundqualität?

The membrane of the Cento CX 690 is made of semi-pressed paper, combined with mica powder, which provides an excellent balance between weight and damping. This construction ensures precise and detailed audio with low distortion. The oval 6" x 9" design allows for optimal bass reproduction and high volume levels. The mechanical damping is further enhanced by the wide rubber surround, designed for high excursion and excellent damping. As a result, the sound remains clear and distortion-free even at high volume, which is particularly noteworthy for music lovers.

Welche Leistung bietet der Cento CX 690 Lautsprecher?

The Hertz Cento CX 690 is a powerful 3-way coaxial speaker with an RMS power handling of 100 watts and a peak power handling of 300 watts. It is designed for high loads, allowing for powerful and dynamic music playback. The speaker has an efficiency of 93.5 dB, which means it can achieve significant sound pressure even at lower amplifier power levels. With an impedance of 4 ohms, it is compatible with most car audio amplifiers, making it versatile for use in various audio systems. The high performance ensures an exceptional listening experience.

Welche Techniken verbessern die Hochfrequenzwiedergabe im Cento CX 690?

The Cento CX 690 uses a 40 mm tweeter to achieve efficient and distortion-free high and mid-frequency reproduction. This is complemented by a 20 mm super tweeter, specifically designed to maximize the level of very high frequencies, even in a horizontal installation position. The geometry of the tweeter faceplate has been optimized using FEM simulations (Finite Element Modeling). This technique ensures a linear frequency response and minimizes distortion, which is particularly advantageous in off-axis installations, as the sound remains balanced and the highs crystal clear.

Wie tragen die Magnetmaterialien des Cento CX 690 zur Klangqualität bei?

The Cento CX 690 from Hertz uses high-density ferrite magnets in the woofer, optimized to work with low-carbon pole plates to minimize distortion. The tweeter relies on neodymium magnets, known for their high energy efficiency, enabling precise high-frequency reproduction. This combination of magnetic materials supports excellent acoustic performance, resulting in detailed and powerful audio playback. The high density of the woofer magnets significantly contributes to bass reproduction by allowing strong, resonance-free vibrations.

Welche Frequenzbereiche deckt der Cento CX 690 ab?

The Cento CX 690 has a wide frequency range of 40 Hz to 23 kHz, which means it can reproduce deep bass as well as very high frequencies. This bandwidth ensures that both the lowest bass notes and the finest high tones are detailed and clear. Particularly noteworthy is the speaker's ability to reproduce deep bass extremely powerfully despite its size, while the super tweeter finely resolves the highs. This allows for comprehensive coverage of all frequency ranges important for music and ensures a thoroughly satisfying listening experience.

Welche Installationshinweise gibt es für den Cento CX 690?

The Cento CX 690 is designed for horizontal installation and offers a variety of installation options with its dimensions of 238 mm in width, 224 mm in depth, and 95 mm in height. The speaker can be installed in many vehicles, taking into account the installation depth of 78.5 mm.

This versatile design significantly simplifies integration into existing car audio systems, as it provides stable mounting points and a harmonious aesthetic.

Wie wirkt sich die Schwingspule des Cento CX 690 auf den Klang aus?

The Cento CX 690 features a midrange and bass driver voice coil with a diameter of 30 mm, allowing for excellent control over the bass driver. This design helps ensure that even at higher volumes, the bass remains powerful and precise. The tweeter uses a voice coil with a diameter of 28 mm for maximum distortion-free high-frequency reproduction. These voice coils enable quick and accurate movement of the membranes, ensuring a smooth and dynamic sound reproduction that supports even the most demanding listening enjoyment.

Was sind die Vorteile des Lautsprechergitters im Cento CX 690?

The speaker grille of the Cento CX 690 is made of highly durable ABS plastic and features a metallic finish. This combination of materials provides effective protection for the speaker components against physical damage and external influences, while the metal grille does not impair sound radiation. Additionally, the grille offers an elegant appearance that contributes to the high-quality look of the speaker. This construction ensures that the acoustic quality is maintained and that the visual and mechanical requirements of a modern sound setup are met.

Warum ist der Hertz Cento CX 690 für hohe Lautstärken geeignet?

The Hertz Cento CX 690 is designed for high volumes, as it has a high load capacity of up to 300 watts peak power.
