Milestones in loudspeaker design.

After extensive studies, calculations, trials and a few sleepless nights PIEGA was able to create the world’s first single dipole system that combines the uniqueness of the coaxial ribbon system and the essential elements of slim-line column loudspeakers. A passion for innovations and maximum technological performance led to the coaxial ribbon system that emitted not only the high frequency range, but also the entire mid-high range on the X-, Y – and Z- axis from the same point.

An idea becomes a reality.

Another approach describes the so-called line source as the ideal transducer. In the case of the line source, all frequencies are radiated as coherent cylindrical sound waves – a principle for which the PIEGA ribbon loudspeaker technology would be eminently suitable. Furthermore, since the degree of distortion increases linearly with the deflection of the membrane on each loudspeaker, the line source (whose sound-producing surface is considerably greater than with conventional speakers) exhibits only extremely low distortion.

Combination as a cornerstone.

This the idea was born to combine both approaches and to develop one line source with several ribbons. In several years of development, the PIEGA Master Line Source was born, whose tweeter/midrange panels were ultimately each equipped with 24 ribbon tweeters and nine used as dipole ribbon midranges and in each of whose subwoofers six 22 cm basses are used.
