Supreme 2

Coltrane Loudspeakers
Coltrane Series
Supreme 2

Our goal was simple. To design the best speaker in the world. With the Coltrane Supreme 2, we’ve arrived at where we want to be. Our ultimate design.

To create the ultimate speaker, we needed an absolute reference point. We recorded our own album, ‘Supreme Sessions.’ The result?

With eyes closed, the playback of the recording is identical to the live performance. The live feeling of the music, played by the musicians at the point of the recording, is reproduced in every detail.
