About this gear
The Coltrane Supreme Extreme is Marten's ultimate flagship floorstander, a statement design built with diamond and ceramic drivers to achieve extraordinarily low distortion and extended treble resolution. It's intended for uncompromising audiophiles building reference-level systems, where transparency, micro-detail, and soundstage depth matter more than convenience or price. Named after jazz legend John Coltrane, it reflects Marten's design ethos of marrying musicality with cutting-edge driver engineering.
