Arcosia 4-208 by ETON

The Eton Arcosia 4-208 4-inch mid-woofer features a dynamic diaphragm geometry made of magnesium composite materials, delivering an authentic sound. The hand-coated dust cap and the flow-optimized motor design support a balanced and detailed sound impression.

The Arcosia series represents the highest musical demands ever placed on a speaker chassis. Arcosia stands for uncompromising sound quality.

The anodized magnesium diaphragm was perforated in an extremely elaborate process and coated with an olefin film. These perforations, combined with the covering olefin film, form fine, bubble-shaped bulges that act like small partial vibration absorbers, largely preventing the formation of all modes. In addition, this fusion of the two components offers a more than exclusive appearance, unmatched in the speaker chassis market.

The special two-component diaphragm technology gives the Arcosia series excellent musical properties, especially expressed in an excellent tonal balance and warm sound character. The soundstage is rendered authentically and with impressive ease, creating the impression of a multi-channel system. Additional attention was given to the ferrite magnet system.

Due to the special design of the magnet geometry, the magnetic field is almost perfectly symmetrical to produce excellent vibration behavior. The particularly effective ventilation of the magnet system with optimal air circulation and heat dissipation minimizes compression effects during dynamic music passages and large amplitudes.

The mechanical quality factor (Qms) is 6.11, while the electrical quality factor (Qes) is at 0.42. The total quality factor (Qts) records a value of 0.39. The moving mass (MDM) is 4.5 g and the inductance of the voice coil (Le) is 0.35 mH with a force factor (BL) of 4.3 Tm. These parameters contribute to the excellent performance and sound fidelity of the speaker.

Welche Belastbarkeit hat der Arcosia 4-208 Lautsprecher?

The ETON Arcosia 4-208 speaker has an RMS power handling of 50 watts. This means it can be continuously operated at a power of 50 watts without the risk of overload. This capability is ideal for demanding applications where clear and strong audio output is required. The effective ventilation of the magnetic system ensures optimal heat dissipation, minimizing the risk of compression effects at high volumes.

Wie beeinflusst die Membrangeometrie den Klang im Arcosia 4-208?

The membrane geometry of the Arcosia 4-208 with an anodized magnesium membrane has a decisive impact on the sound. The perforations of the membrane, combined with the olefin film, create fine bulges that prevent the formation of modes. This optimizes sound quality by reducing unwanted sound waves and facilitates precise sound reproduction. The special motor design, along with the symmetrical magnet geometry, enables a balanced oscillation behavior and thus a sound precision that is crucial for detailed music playback.

Wie wird die tonale Ausgewogenheit beim Arcosia 4-208 erreicht?

The tonal balance of the Arcosia 4-208 is achieved through innovative two-component membrane technology. The magnesium membrane is equipped with perforations that are balanced with an olefin film. This structure acts as an absorber for partial vibrations. The perfectly calibrated magnet geometry produces an almost symmetrical magnetic field, resulting in remarkably uniform vibration behavior. Additionally, the optimized air circulation ensures constant cooling and efficiency of the system, keeping the reproduction in terms of frequencies and volume even and warm.

Welche Impedanz hat der ETON Arcosia 4-208 und was bedeutet das?

The ETON Arcosia 4-208 has a nominal impedance of 8 Ω, connected with a DC resistance of 5.8 Ω. An impedance of 8 Ω is standardized and allows compatibility with most amplifiers and audio systems. It affects the electrical integration and efficiency of the speaker in the system circuit. A low DC resistance also supports the signal flow, which improves the dynamics and responsiveness of the speaker regarding the audio input. These characteristics lead to optimized audio performance, especially at high volumes.

The maximum electrical displacement (Xmax) of the ETON Arcosia 4-208 is +/- 4.0 mm, while the mechanical displacement reaches +/- 8.2 mm. This describes the maximum movement range of the diaphragm without distortion. Such displacement is particularly important for producing low frequencies, as it displaces more air to effectively generate these tones. The robust construction and diaphragm technology allow for these displacements to be achieved while maintaining sound precision. Therefore, they are crucial for dynamic musical experiences, especially with deep bass.

Welche Abstrahlfläche hat der ETON Arcosia 4-208?

The ETON Arcosia 4-208 has an effective radiation area of 50 cm². This size allows the speaker to move a considerable amount of air, resulting in a powerful and clear sound image. The radiation area is crucial for the ability to distribute frequencies evenly in the room and to create the widest possible 'Sweet Spot'. A larger radiation area improves bass reproduction and overall volume performance, enhancing the effect of a multi-channel system and fully immersing the listener in the sound experience.

Wie installiere ich den Arcosia 4-208 im Auto hinsichtlich Größe?

When installing the ETON Arcosia 4-208 in the vehicle, compatibility regarding the 10 cm (4") format is important. It is crucial to ensure that the intended installation location provides enough space for the speaker and also for sound development. Before installation, the opening in the vehicle should be checked for the necessary dimensions. Additionally, care should be taken to ensure that the speaker is securely installed to fully exploit all the advantages of its sound quality. Proper sealing and fastening maximize the acoustic performance, especially in dynamic driving situations.

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.

Top Upgrade für Canton System

Ich habe den Woofer in meinem Skoda Octavia 3 mit Canton Soundsystem eingebaut.
Der Einbau war Plug & Play, alles passt perfekt ohne Anpassungen.
Im Vergleich zum originalen Canton Subwoofer spielt dieser deutlich stärker, präziser und mit mehr Druck.
Ich kann den Woofer jedem empfehlen, der mehr Bass aus dem Canton-System herausholen möchte – lohnt sich absolut!
