Arcosia 7-208 by ETON Description

The ETON Arcosia 7-208 is a 6.5-inch (16.5 cm) mid-bass driver. The dynamic diaphragm geometry made from magnesium composite materials and an anodized, perforated magnesium diaphragm with olefin film characterize its construction. The perforations create bubble-shaped bulges that act as partial vibration absorbers. A two-component diaphragm technology, a hand-coated dust cap, and an optimized motor design are integrated. The ferrite magnet system utilizes a symmetrical magnetic field geometry as well as effective ventilation with optimal air circulation and heat dissipation. The frequency range is 50–3000 Hz, the nominal impedance is 8 Ω, and the power handling is 100 watts RMS. Specified parameters include 89 dB (1 W/1 m), a resonance frequency of 31 Hz, Xmax electrically ±5.5 mm and mechanically ±9.5 mm. Other parameters: Qts 0.32, Qms 5.88, Qes 0.34, Le 0.87 mH, BL 8.0 Tm, Sd 137 cm², Mmd 16.3 g, CMS 1.25 mm/N, RMS 0.67 kg/s, and VAS 32.9 liters.

Frequently Asked Questions about Arcosia 7-208

What are the main features of the Eton Arcosia 7-208?

The Eton Arcosia 7-208 features a dynamic membrane geometry made of magnesium composite materials that produces authentic sound. The hand-coated dust cap and the flow-optimized motor design ensure a balanced and detailed sound impression. The special two-component membrane technology with anodized magnesium membrane, perforated and coated with olefin film, prevents modal formation and creates a warm sound. The ferrite magnet system with a special magnet geometry ensures perfect oscillation behavior and minimized compression effects. The effective ventilation allows optimal air circulation and heat dissipation, enhancing sound quality.

How does the membrane geometry of the Arcosia 7-208 affect the sound?

The membrane geometry of the Arcosia 7-208 consists of magnesium composite materials that generate dynamic sound waves. This construction ensures high precision and authenticity in the sound image. The perforated structure of the membrane reduces modal formation through the olefin film, which acts as a partial vibration absorber. This combination of materials and design ensures that even fine sound details are reproduced clearly, which is especially important for high musical demands.

What role does the flow-optimized motor design play in the Arcosia 7-208?

The flow-optimized motor design of the Arcosia 7-208 significantly contributes to a balanced and detailed sound. The special design of the magnet geometry ensures nearly perfect oscillation behavior, as the magnetic field is symmetrical. This symmetry minimizes distortion during sound reproduction. Furthermore, the ventilation of the magnet system improves air circulation and heat dissipation, thereby reducing compression effects, especially during dynamic musical passages.

What are the technical specifications of the Eton Arcosia 7-208?

The Eton Arcosia 7-208 has a frequency range of 50 - 3000 Hz and a power handling capacity of 100 Watts RMS. The nominal impedance is 8 Ω, the DC resistance is 6.5 Ω, and the resonance frequency is 31 Hz. With a compliance of the suspension of 1.25 mm/N and a mechanical quality factor of 5.88. The electrical quality factor is 0.34, and the total quality factor is 0.32. The inductance of the voice coil is 0.87 mH, and the force factor BL is 8.0 Tm. The speaker has a mechanical Xmax of +/- 9.5 mm.

What does the SPL specification mean for the Arcosia 7-208?

The average sound pressure level of the Arcosia 7-208 is 89 dB SPL at 1 Watt/meter, indicating a high efficiency. This means that the speaker is capable of playing loudly with low power, which is particularly important for applications where a wide frequency range needs to be covered without increasing amplifier power. The successful combination of diaphragm geometry and motor design allows the high SPL to produce a detailed and voluminous sound image that shows no distortion even at high amplitudes.

What are the advantages of the two-component diaphragm technology in the Arcosia 7-208?

The two-component diaphragm technology of the Arcosia 7-208 combines a perforated magnesium diaphragm with an olefin film that forms bubble-like bulges and acts as a partial vibration absorber. This technology prevents the formation of modes that could distort the sound and leads to a flowing and harmonious sound characteristic. This unique diaphragm construction not only provides acoustic advantages but also offers an exclusive appearance that stands out in the loudspeaker chassis market.

How does the magnet geometry of the Arcosia 7-208 affect the sound?

The carefully designed magnet geometry in the Arcosia 7-208 ensures an almost perfectly symmetrical magnetic field, which is essential for improved vibration performance. This geometry creates a homogeneous field across the entire voice coil, thereby minimizing sound distortions that can occur with asymmetrical magnetic fields. The resulting sound quality is richer and more precise, especially with dynamic music pieces, as compression effects are significantly reduced.

To what extent does the ventilation system minimize compression effects in the Arcosia 7-208?

The ventilation system of the Arcosia 7-208 is designed to ensure optimal air circulation, enabling efficient heat dissipation. Due to these improvements, the mechanical stress on the components at high volumes is reduced, which enhances sound fidelity during dynamic music passages. This efficient design minimizes compression effects that often occur at high volumes, allowing the sound to remain free and uncolored.

What is the significance of the membrane perforation in the Arcosia 7-208?

The perforation of the magnesium membrane in the Arcosia 7-208, combined with an olefin film, serves to minimize the formation of unwanted modes, resulting in a more uniform sound image. The small bubble-like protrusions created by this technology act as partial vibration absorbers and prevent sound distortion. This technical sophistication allows for exceptional sound reproduction, which is advanced in both sound quality and visual appearance, and is impressive.

What are the dimensions and installation depth of the Eton Arcosia 7-208?

The dimensions of the Eton Arcosia 7-208 correspond to a standard of 6.5 inches (6.5 inches) in diameter, making it ideal for a variety of installation locations. The speaker is equipped with an effective radiation area of 137 cm², further optimizing the footprint. The installation depth of the product allows it to be used in a variety of speaker enclosures or car installations, enabling the user to benefit from the excellent sound qualities without limitations.
