Here and Now

Josef Sperl, himself a musician, started a music business and built himself loudspeaker boxes, which were very well received by professional bands. It was followed by tube amp production for guitar, bass and finally also that interest of the specialized trade aroused.

Well-known pop singers and gala bands of that time such as Bata Illic, Vico Torriani, Heidi Brühl, Ireen Sheer, Les Clochards, Ambros Seelos, Contis etc. were fully convinced of the perfect sound quality of the SOLTON products. In 1975/76 Fats Domino and Bill Haley (King of Rock'n Roll) went on a European tour with complete SOLTON equipment.

SOLTON rotor cabinets, professional organs and keyboards have become big sellers internationally. 

Major events such as Olympia Sarajevo, Hahnenkamm race Kitzbühel and many others were sonicated with SOLTON and aa craaft facilities.

Josef Sperl, who still makes music today with his band "Oldie Express", continues to be responsible for the sound design of today's products. Son Sebastian Sperl, singer of Alternative Metal band "ALSO AM I" is responsible for the technical support.


The successful current product range offers the optimal selection for every music genre. SOLTON Acoustic is currently exporting to 28 countries, the brands "SOLTON" and "aa craaft".
