Beschreibung
The Arcosia series, which includes the ETON 7-218 ARCOSIA 6.5" (16.5cm) woofer represents the highest musical demands ever placed on a loudspeaker chassis. Arcosia stands for uncompromising sound quality.
The dynamic cone geometry made of magnesium composite materials produces an authentic sound. The hand-coated dust cap and the flow-optimized motor design support the balanced and detailed sound impression.
The anodized magnesium membrane was perforated in an extremely complex process and covered with an olefin foil. These perforations, in combination with the covering olefin foil, form fine, bubble-shaped bulges that act like small partial vibration absorbers and thus largely prevent the formation of all modes. In addition, this fusion of the two components offers a more than exclusive look that is unrivaled on the loudspeaker chassis market.
The special two-component membrane technology gives the Arcosia series outstanding musical properties, which are expressed above all in an excellent tonal balance and warm sound characteristics. The sound space is presented authentically and with impressive ease, giving the impression of a multi-channel system. Additional attention was paid to the ferrite magnet system.
Due to the special design of the magnet geometry, the magnetic field is almost perfectly symmetrical in order to generate excellent vibration behavior. The particularly effective ventilation of the magnet system with optimal air circulation and heat dissipation ensures minimized compression effects in dynamic music passages and large amplitudes.
They rightly and proudly called their Arcosia series the "milestone of sound"!
