Mechanical details of the ETON midrange speaker weighing 1.2 kg

The ETON 3-212/C8/25 HEX midrange driver brings a mechanical robustness with its total weight of 1.2 kg, which is highly valued in the car audio sector. A mounting diameter of 96 mm and a total depth of 66 mm make it ideal for various installation environments in the vehicle. A surround of 6 mm and a total diameter of 122 mm emphasize the solid mechanical properties. These dimensions are optimal for precise installation and prevent unwanted resonances, which can potentially improve acoustic performance when integrated correctly.

Efficiency increase through innovative Hexacone sandwich membranes

The three-layer Hexacone sandwich membrane of the ETON midrange driver gives it its unique sound characteristics. This membrane ensures a remarkable reduction in distortion, resulting in clearer and uncolored midrange frequencies. The choice of materials and structure can easily support frequencies in the range of 100 to 5400 Hz. A conventional membrane would show more distortion under the same load. This construction offers superior stiffness and minimizes acoustic interference, resulting in a freer sound field.

Efficiency of 88 dB and its significance in the car audio sector

The efficiency of 88 dB makes this midrange speaker an excellent choice for vehicles with demanding acoustic environments. A high efficiency means that the speaker can produce more sound pressure from less energy. Compared to speakers with lower efficiency, these require more input voltage to achieve the same volume, making the ETON unit more efficient, even when integrated into a passive speaker system. For drivers who focus on energy optimization while maintaining sound output, this midrange speaker is ideal.

The optimized frequency range of 100 - 5400 Hz for excellent midrange.

An optimized frequency range of 100 to 5400 Hz ensures that this 3 midrange driver effortlessly handles the critical mid frequencies that are essential for the human voice and many instruments. This allows audiophiles to discover fine details in the sound image that are often lost in the higher and lower frequencies. Midrange drivers that cover a narrower frequency range may struggle to deliver such fidelity, which sets the ETON driver apart from many standard models.

Resonance frequency of 57 Hz and its influence on sound quality

The resonant frequency of 57 Hz indicates the natural frequency at which the midrange driver would vibrate without external drive. A lower value in this range indicates that the speaker can represent more bass. In the context of the midrange driver, this value is an optimal mix for the intended application – it shows that the speaker not only supports excellent midrange but also extends into the lower sound areas. If this value were lower, the design could be optimized for deeper frequencies, which, however, is rarely required in the midrange.

Details and advantages of the copper coil of the ETON speaker

The copper voice coil, embedded in Kapton, significantly contributes to the overall efficiency of the midrange driver. Copper is known for its excellent electrical conductivity, ensuring efficient energy transfer, while Kapton, with its high temperature resistance, provides a stable base for this coil. By using two winding layers, a high fill factor is achieved, resulting in better control over the magnetic flux. A lack of such component-specific advantages could lead to performance degradation due to overheating or instabilities.

Power factor of 5.8 Tm and its influence on performance

The force factor of 5.8 Tm is a crucial performance indicator, as it describes the product of the magnetic field in the air gap and the length of the conductor that traverses it. A higher force factor leads to stronger control and improves the overall linearity of the unit. In the car audio industry, values between 5 and 7 Tm are common for midrange drivers of this size, which puts the ETON speaker in a favorable position. If this value were lower, the control of the diaphragm movement would be less stringent, potentially leading to a noticeable deterioration in sound quality.

Installation diameter and magnetic system of the ETON midrange speaker

With a mounting diameter of 96 mm, the ETON midrange driver can be flexibly integrated into various vehicle configurations. The overhung drive system ensures high efficiency of the magnetic system. The ferrite material provides a magnetic flux density of 1.15 T and optimizes the energy flow in the motor. Conventional magnets with lower flux densities would result in a less efficient conversion into acoustic energy, which highlights the ETON midrange driver in comparison.

The influence of Kapton as a carrier material for the vibrating coil

Kapton as the carrier material of the ETON midrange driver enables high thermal stability, while copper guarantees optimal conductivity. This combination ensures that the midrange driver maintains high performance without the risk of distortion or thermal degradation. With less suitable materials, such factors could be inadequate and lead to rapid aging or deformation of the carrier material. The use of Kapton significantly optimizes the durability and performance of the speaker. Would you like to learn more about the installation of the speaker?
