A fleet ahead of the rest.
The flagship Coltrane series came to the stage in 2003, establishing Marten as a major player in the high end market, winning many awards along the way.
Coltrane has always led innovation and pushed technology at Marten. It was the first to use Cell drivers by Accuton and the first order crossover we have become famous for. The first order crossover creates absolute perfect time and phase coherence; flawless time coincidence has incredibly low distortion, even at high levels.
The Coltrane series is the ultimate reference in sound reproduction, with extreme clarity, speed and resolution; itβs uncannily musical even at low volume.
