Tonträger (Stereo set)

Loudspeakers that combine excellent sound with unique design.

Why the loudspeakers are called “Tonträger”(Sound carrier):
This does not mean the medium for storing music. These “Tonträger” transport the sound into the room.
In German “Ton” is a homophon and has two meanings: sound and clay.
One could also speak of “tone in ton” or ton2, because in this exclusive product, hand-shaped clay (ton) meets modern hi-fi sound (ton) technology from ABACUS electronics.

In addition to the material, the production of the “Tonträger” is also special – the spherical barrel shapes are throwed by hand on the potter’s wheel. The selected clay mass and the high firing temperature ensure a scratch-resistant and hard housing material. Fully assembled, the “Tonträger”  are fired tightly at 1280 ° C with a clay glaze. The completely glazed surface forms a harmonious connection with the anodized adapter rings and the tweeters and bass-midrange drivers attached to them. That glaze will be available in different colors in the future.


A stable and hard material is essential for hi-fi speakers. The clay mixture used with its high degree of hardness, as well as the round bevels ensure an incomparable sound experience.


The curved and lively design ensures the unique sound and is a must-have for every retro fan.


The load-independent amplifiers from ABACUS (made in Northern Germany) convince in this delicate ceramic combination with high speed and precision in signal processing.


In addition to soft and round basses, which are still audible even at low volume, the Wavecor drivers also impress in the midrange with clear voices and a linear sound.

The tones of the remaining octaves find their way seamlessly and precisely from the tweeters and complete the crystal-clear sound of the “Tonträger”.
