Frequently Asked Questions about Graphite 80

Welche technischen Merkmale definieren den Graphit 80 von ETON?

The Graphit 80 from ETON is a 3-inch midrange driver with a unique carbon fleece sandwich membrane for excellent acoustic performance. It features an anodized aluminum dust cap that ensures efficient heat dissipation. The strong neodymium magnet and the reinforced ventilated aluminum die-cast basket provide stability and minimize distortion. The speaker has a nominal power of 25 W RMS and a music handling capacity of 40 W at an impedance of 4 Ohms. The characteristic sound pressure is 86 dB, indicating high sensitivity. Made in Germany, it combines power and precision in one.

Wie wirkt sich der Neodym-Magnet im Graphit 80 aus?

The powerful neodymium magnet in the Graphite 80 plays a crucial role in the efficiency and sound quality of the midrange driver. Its high energy density allows for powerful sound output in a compact size. Together with the reinforced architecture of the aluminum die-cast basket, it reduces unwanted vibrations and resonances, resulting in a clearer and more precise sound image. This combination of magnet and material ensures a durable, stable performance that particularly shines at high volumes. Additionally, it contributes to improved transient response, which provides excellent dynamics.

Was sind die Hauptkomponenten der Membran im Graphit 80?

The membrane of the ETON Graphit 80 consists of a carbon fleece sandwich that offers exceptional acoustic properties. This construction combines lightness and stiffness, minimizing distortion and allowing for fast transients. The sandwich structure ensures that the membrane remains shape-stable even under intense use and enables precise, color-free sound reproduction. The integration of an anodized aluminum dust cap not only optimizes heat dissipation but also provides the midrange driver with an additional protective layer that can increase the lifespan of the speaker.

Welche Thiele-Small-Parameter sind für den Graphit 80 relevant?

The Thiele-Small parameters of the Graphit 80 include several important measurements: The resonance frequency is 129 Hz, while the mechanical Q factor (QMS) is 6.27, indicating the mechanical damping potential. The electrical Q factor (QES) is 0.67, describing the electrical efficiency. The total Q is 0.61, combining mechanical and electrical damping properties. The force factor BL is 4.4 Tm, which clearly indicates the control by the speaker. The Xmax of +/-5.4 mm indicates the mechanical displacement capacity, ideal for nuanced low-frequency performance.

Wie lautet die Leistungsspezifikation des ETON Graphit 80?

The performance specifications of the ETON Graphit 80 can be summarized as follows: The midrange driver has a nominal power of 25 watts RMS, indicating how much continuous power it can safely handle. The music power handling, or how much peak power the midrange driver can take for short periods, is 40 watts. These values at an impedance of 4 ohms make the speaker versatile for a wide range of audio applications. Additionally, the characteristic sound pressure level of 86 dB at 1 W/1 m is responsible for high sensitivity and allows for dynamic sound reproduction even at lower power levels.

Welche Vorteile bieten die Aluminium-Staubkappe und der Druckgusskorb beim Graphit 80?

The combination of anodized aluminum dust cap and aluminum die-cast basket in the Graphit 80 offers several advantages. First, the dust cap optimizes heat dissipation, reducing thermal stress even during intense use. This contributes to extending the lifespan of the midrange driver. Second, the ventilated aluminum die-cast basket provides structural rigidity without additional weight, thereby minimizing distortion. It ensures a dimensionally stable environment that stabilizes the speaker's performance, especially at high volumes. This construction guarantees protection and superior sound characteristics.

Wie sieht die Installation des ETON Graphit 80 hinsichtlich der Abmessungen aus?

For the installation of the ETON Graphit 80, knowledge of the exact dimensions is crucial. The midrange driver measures 3 inches, or 80 mm, in diameter, which should be considered when choosing the installation location. The compact size facilitates integration into various vehicle interiors, but it should be ensured that there is enough space for the reinforced aluminum die-cast basket to minimize vibrations. It is recommended to use a professional tape measure or measuring device to accurately account for these dimensions and ensure a perfect installation experience without subsequent adjustments.

Wie beeinflusst die Impedanz des Graphit 80 die Audioinstallation?

The impedance of the Graphit 80 is 4 ohms, a crucial parameter for planning an audio installation. A lower impedance means that the speaker can draw more power, which typically results in higher volume. However, it is important to ensure that the amplifier or audio system is compatible to guarantee optimal performance. If the impedance is not correctly matched, it could lead to overloads or even damage. For the ETON Graphit 80, the amplifier power should remain within the rated capacity of 25 to 40 watts RMS.

Warum ist der Graphit 80 ideal für High-End-Audioanwendungen?

The Graphit 80 impresses with its unique attributes, making it particularly suited for high-end audio applications. The carbon fleece sandwich membrane, combined with the powerful neodymium magnet, enables exceptional detail fidelity and sound clarity. The meticulously shaped aluminum dust cap ensures excellent heat dissipation. With a resonance frequency of 129 Hz and a voice coil diameter of 25 mm, it stands out for remarkable bass performance and stability. Developed in Germany, this midrange driver combines precision and reliability to meet high demands in challenging audio settings.

Welche Rolle spielt der Schalldruck des Graphit 80?

The characteristic sound pressure of the Graphit 80 is 86 dB at 1 Watt/1 meter. This value is an indicator of the sensitivity and efficiency of the speaker. A higher sound pressure level means that a higher volume can be achieved with lower power input, which in turn reduces the demands on the amplifier. This efficiency is particularly advantageous in mobile applications, where power output can be critical. The high sound pressure also ensures that even the finest musical details can be reproduced accurately, which is of particular interest to audiophile users.
