Frequently Asked Questions about Onyx 16

What impedance does the ETON Onyx 16 Mid-woofers have?

The ETON Onyx 16 Mid-woofers has an impedance of 4 Ohm. This impedance is a crucial factor for power transfer and directly affects compatibility with Amplifiers. With a 4 Ohm impedance, Amplifiers can operate efficiently to maximize sound performance. The low impedance also allows the speaker to draw more current at a given voltage, contributing to higher acoustic output. Especially in more complex car systems, impedance plays a significant role in optimizing the balance between the speaker and the Amplifier. A lower resistance can also mean that at maximum volume, lower distortion occurs.

What power can the ETON Onyx 16 handle?

The ETON Onyx 16 offers a nominal power handling of 90 Watts RMS and a music power handling of 140 Watts. These power ratings indicate that the speaker can continuously handle 90 Watts without damage, making it ideal for continuous use. The higher music power handling of 140 Watts, on the other hand, suggests that the speaker can manage short, power-intensive peaks that often occur in music without distortion or overheating. This is particularly useful when high levels are desired in dynamic music without compromising sound quality.

What are the physical dimensions of the ETON Onyx 16?

The ETON Onyx 16 has an overall diameter of 165 mm and a cut-out diameter of 146 mm. The frame depth is 6 mm, while the installation depth measures 79.5 mm. These precise measurements make the speaker an ideal option for many common installation locations in vehicles, but also offer flexibility in placement, as a flatter design often provides more mounting options. Looking at the screw holes, they are 4.5/8 mm in diameter. Therefore, the dimensions are essential when planning the speaker installation to ensure that there is enough space and suitable mounting options available.

What materials and construction are used in the ETON Onyx 16?

The ETON Onyx 16 features a ribbed and reinforced paper diaphragm as well as a hand-painted dust cap made of fabric. These materials are known for their excellent acoustic properties, providing a precise and balanced sound profile. The Mid-woofers are held by an aluminum die-cast basket that is extremely torsionally rigid to minimize resonances. Additionally, the speaker contains a strong neodymium magnet, known for its high magnetic flux and small size. This thoughtful choice of materials and construction ensures long-lasting use as well as outstanding sound quality and mechanical stability.

How do the Thiele-Small parameters affect the performance of the ETON Onyx 16?

The Thiele-Small parameters of the ETON Onyx 16, including QMS (5.07), QES (0.78), QTS (0.68), and VAS (8.6 dm³), are crucial for sound reproduction. The mechanical Q factor QMS indicates the mechanical damping, while the electrical Q factor QES represents the electrical damping. QTS as the total damping factor is an indicator of the interplay between the two. The VAS value shows the equivalent volume that allows the diaphragm to move freely. Together, these values lead to a balanced bass reproduction. The high mechanical Xmax of +/- 9.0 mm also allows for large diaphragm excursions, enabling dynamic deep bass.

What installation tips are there for the ETON Onyx 16 in a car?

When installing the ETON Onyx 16 in a car, the installation depth of 79.5 mm is an important aspect. One should ensure that the intended installation position provides enough space to install the speaker without complications. The cut-out diameter limit of 146 mm means that the speaker must be fitted precisely to avoid unnecessary vibrations. The diameter of the screw holes of 4.5/8 mm for mounting should also be considered to ensure a secure and stable installation. Adequate ventilation can further optimize performance by dissipating heat.

What sound pressure level does the ETON Onyx 16 offer?

The ETON Onyx 16 produces a characteristic sound pressure level of 88 dB at 1 Watt/1 meter. This value is crucial when assessing the efficiency of the speaker in an audio system. A higher sound pressure level means that less power is needed to achieve a high output level. With 88 dB, the Onyx 16 offers strong sound quality even at lower amplifier powers. Especially if you enjoy listening to music loudly without having to push your amplifier to the maximum, a high sound pressure level is advantageous. This minimizes distortion while maintaining focused power transfer.

What frequency response can be expected from the ETON Onyx 16?

Although the specific frequency response curve is not provided, the resonance frequency of the ETON Onyx 16 at 77 Hz suggests a capable bass reproduction. The resonance frequency is the point at which the speaker can naturally resonate, leading to excellent low-frequency reproduction. Combined with materials like the reinforced paper diaphragm, a prominent bass response is expected alongside clear mid frequencies. Comprehensive frequency coverage ensures that the speaker can cover a variety of music genres, achieving a natural and precise sound without drastic peaks.

How does the type of magnet affect the performance of the ETON Onyx 16?

The ETON Onyx 16 uses a strong neodymium magnet, known for having significantly more magnetic flux per volume than conventional magnets. Neodymium magnets allow for a more compact design of the speaker while maintaining high energy efficiency. This ensures that the coil operates optimally in the magnetic field, enabling better transient response and detail of the audio signal. With enhanced magnetic performance, the speaker achieves more precise diaphragm control, which is invaluable for reproducing complex audio signals and contributes to the accuracy of music playback.

In what way is the voice coil in the ETON Onyx 16 unique?

The voice coil of the ETON Onyx 16 has a diameter of 32 mm and is ventilated, ensuring effective heat dissipation. A well-ventilated coil prevents overheating, especially at high power levels or during extended operation. The winding with symmetry ensures that current and associated magnetic forces are evenly distributed, further enhancing sound clarity. Additionally, the precise control of the voice coil movement allows for accurate reproduction of audio signals. This is particularly important for keeping distortion low and producing a smooth, delay-free sound.
