      Product details

      ETON 4-218 ARCOSIA Bass-mid Woofer

       

      The Arcosia Series stands for the highest musical requirements ever posed to a loudspeaker chassis. Arcosia is uncompromising sound quality.

       

      The anodized magnesium cone was perforated in an extremely elaborate procedure and covered with an olefine film. In interaction with the covering olefine film, these perforations form fine, bubble-shaped arches, which work like small partial vibration absorbers and therefore prevent the development of all modes to the greatest possible extent. In addition, this merger of the two components offers a more than exclusive appearance, which is second to none on the loudspeaker chassis market.

       

      The special two-component cone technology confers excellent musical properties to the Arcosia Series, primarily expressed by its excellent tonal balance and warm sonic characteristics. Sonic space is authentically represented with striking nonchalance, giving rise to the impression of a multichannel system. Additional attention was paid to the ferrite magnet system.

       

      The magnet geometry’s special design makes the magnetic field almost perfectly symmetrical in order to generate excellent vibration behavior. The particularly effective ventilation of the magnet system, with its optimum air circulation and heat dissipation, ensures minimized compression effects in dynamic musical passages and large amplitudes.

       

      We have justifiably and proudly called our Arcosia Series the “Milestone in Sound”!
