Your advantages with Masori


Experience the impressive audio quality of the ETON 7-312/C8/32 HEX: 80 Watt load capacity.

The ETON 7-312/C8/32 HEX 8 (20cm) midrange driver impresses audio enthusiasts with a power handling of 80 watts. This ensures an ideal balance between sound quality and robust performance, enabling the speaker to reproduce both deep bass and precise mids with fidelity. A high power handling value means you can operate the speaker at higher power levels for extended periods without compromising sound quality or risking overload. In the car audio world, speakers with around 50-100 watts are commonly used, placing the ETON speaker in the upper range. At masori.de, you can purchase the ETON 7-312/C8/32 HEX at a low price and benefit from the Masori lowest price guarantee.

Optimal frequency reproduction with the recommended frequency range of 50 to 3000 Hz

Thanks to a recommended frequency range of 50 to 3000 Hz, the ETON mid-bass speaker covers a wide range of sound frequencies, allowing both deep bass and clear mids to be optimally showcased. This frequency range enables you to reproduce music pieces in a detailed and dynamic manner. Especially in the world of car audio applications, such a wide frequency range is desirable as it can support a greater variety of music genres and adapt the system more flexibly to your listening preferences. Comparable speakers in this category often have a narrower frequency range, which makes this ETON speaker particularly versatile.

Outstanding mechanics with a coil diameter of 32 mm

The voice coil of this midrange driver has been manufactured with special attention to precision and durability. With a diameter of 32 mm, made from Kapton and copper, the voice coil offers stability and efficiency in converting electrical signals into mechanical movement. This feature significantly contributes to a clean and controlled sound image, even at higher power levels. Within the car audio scene, this is considered a sign of quality, as larger voice coils ensure better heat distribution and mechanical robustness, thus contributing to a longer lifespan of the speaker.

Technical perfection through the power factor BL of 8.8 Tm

The powerful force factor BL of 8.8 Tm underscores the efficiency of the ETON 7-312/C8/32 HEX in driving the diaphragm. A high BL value means that the speaker can exert more force on the diaphragm at lower voltage, which supports the responsiveness and precision of the sound. For speakers in the car hi-fi sphere, such a high BL value is an indicator of an excellent balance of power and control, which is particularly desirable in dynamic music genres.

Precise sound through a resonance frequency of 35 Hz

The resonance frequency of 35 Hz indicates that the mid-bass driver is particularly capable of accurately reproducing lower bass frequencies. A lower resonance frequency means that the speaker can dive deeper into the bass range, which is especially beneficial for music styles characterized by strong bass lines. This specification makes the ETON speaker an exceptional choice for car hi-fi systems that require rich and dynamic bass. Most mid-bass drivers are in the range of 50 to 60 Hz, which makes the ETON particularly powerful.

Powerful sound reproduction through a magnetic flux density of 1 T

The ferrite magnet system of the speaker provides a magnetic flux density of 1 T, significantly enhancing the speaker's ability to convert electrical signals into sound. Such a high value of magnetic flux density means more efficient movements of the diaphragm, resulting in clearer and more precise audio reproduction. In car audio technology, such a flux density represents outstanding sound fidelity and efficiency, allowing even complex sound structures to be reproduced in detail and with impact.

Efficiency improvement through mechanical quality Qms of 6.4

With a mechanical quality factor Qms of 6.4, this mid-bass driver demonstrates impressive efficiency in converting mechanical energy. A higher Qms value indicates excellent mechanical control, which increases the durability and lifespan of the speaker. Comparatively, the Qms in this product category often ranges from 4 to 7.5, making the ETON value a perfectly balanced technical characteristic. This quality gives the speaker a performance capacity that impresses under various installation conditions in the car.

Xmax mechanical of ±8.8 mm for an impressive sound image

The maximum displacement value Xmax mechanically of ±8.8 mm allows for powerful and precise bass reproduction, as the diaphragm can swing widely without producing audible distortions. Such displacement is excellent for the dynamic reproduction of powerful bass lines within a car hi-fi system. Speakers in similar categories often offer lower Xmax values in the range of ±5 to 7 mm, which gives the ETON model a decisive advantage in terms of dynamics and volume.

Low direct current resistance Re of 6.7 Ω supports sound fidelity.

The DC resistance Re of 6.7 Ω contributes to the speaker's compatibility with various amplifiers and allows for smoother integration into a large car audio system. In combination with a nominal impedance of 8 Ω, this resistance provides the foundation for efficient and stable sound reproduction. Choosing a suitable amplifier is easier since this value falls within the usual range for speakers, thus facilitating installation.

Persuasiveness through precise mid-range reproduction: Effective radiation surface SD

With an effective radiation area SD of 137 cm², the ETON 7-312/C8/32 HEX offers efficient sound distribution in your vehicle. A larger radiation area ensures that the sound is distributed clearly and distinctly in the space, making more powerful mid-range reproductions particularly stand out. This enhances the stage representation and overall audio experience when listening to music during your drives. Installation on site in Frankfurt (Oder) Expert support FAQ & Help Audio Blog
