Sphäron "Excalibur"

Developed from the "classical" Sphäron, the new Excalibur is raising to a new standard of dimension and variability. In consideration of the fact that the former Sphäron had to be combined with a 12m² horn unit for transmission of the lowest frequencies, the new Excalibur now can easily be integrated into living rooms having a minimum size of 40m². Two towering pillars with four huge 15 inches woofers for each unit now are taking over the part of the low frequency horn unit.

This loudspeaker system has no limits: with a 15 watt power already, music will be reproduced three-dimensional, thus giving you the illusion to be a member of the orchestra or the band. From the softest, perceptible sounds, these loudspeaker sculptures can accelerate the music like lightning, comparable only with the spurt of a racing car.

When the music is soft, the sounds caress your skin. When it changes into a powerful fortissimo,the listener will be swept away to the epitome of joy.
