Marten Coltrane 3

The new Coltrane 3 is a landmark creation, a technical tour de force that brings together Marten’s most advanced research and sound engineering to date. It features the same ground-breaking technology first developed for the Coltrane Supreme 2, all beautifully packaged in a more lounge-friendly form.

From the cabinets to the smallest components, the Coltrane 3 uses exclusive, premium materials to continue the Coltrane commitment to superior structure and sound. First order filters and CELL concept drivers developed in partnership with Accuton deliver a sound that is perfectly time and phase coherent. The tweeters, midrange and bass drivers have identical acoustic centres to give outstanding timing and flow. And distortion is unbelievably low, for superb levels of detail and resolution, with minimal colouring of the sound, even at high volume.

These 3 way speakers employ the newly developed Cell drivers. The Cell tweeter cone is made of pure diamond
The Cell mid range unit is made from a new pure ceramic, premiered in Coltrane 3. 1st order crossover – a feature first developed for the Coltrane Supreme 2. Based on the joint venture with Accuton and their CELL technology, it creates a sound that is 100% time and phase coherent. Front – extremely rigid featuring a new aluminium layer sandwiched between two wooden layers.

• Stand – bigger and sturdier than Coltrane 2
• Wheel mounts – for easy handling and fine-tuning
• Superior Bass control – a greater selection of levels 
• Finishes – available in a new wider selection of colourways and finishes

CELL concept drivers

Our joint venture with Accuton represents a new milestone in hi-fi history. Accuton developed the unique CELL concept drivers used within the Coltrane Supreme 2. Tweeters, midrange and bass drivers have identical acoustic centres, delivering flawless phase and time coherency. The domes in the units are perfectly rigid, for impeccable signal settle and piston behaviour. And there is incredibly low distortion, in the magnitude of electronic devices, even at high levels.

• Steady decay of higher order harmonics
• High bandwidth.
