The Diamond standard.

Coltrane Supreme 2 uses Cell technology diamond tweeters and ceramic bass units, tailor-made in a joint project with Accuton.

The tweeters, midrange and bass drivers have identical acoustic centres, delivering flawless phase and time coherence. The domes in the units are perfectly rigid, for impeccable signal settle and piston behavior. It has incredibly low distortion, even at high levels.

  • Steady decay of higher order harmonics
  • High bandwidth
We never follow the path of least resistance.

Marten worked tirelessly to refine the crossover so it would work perfectly with Accuton Cell drivers. It wasn’t an easy task, but it was the clear solution.

The first order crossover makes it possible to have perfect time and phase coherence; and flawless time coincidence. This means that all registers are generated at the exact same moment, as it was recorded. Just like live music.
