COLTRANE 3
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 to choose from
• 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 3. 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
