Tried and tested.

Coltrane 3 uses Cell technology developed especially for our speakers in a joint project with Accuton. The diamond tweeters and ceramic bass units are the same as those in our landmark Supreme 2 model.

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
Crossover
We saw the path of least resistance. And went the other way.

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. It’s success has defined the sound for a new generation of Marten speakers.

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, just as it was recorded. The sounds reach your ears as if the music were live.

"This model upholds our philosophy of truth in music, by faithfully reproducing sound exactly as you hear it in reality."
