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
