Marten Coltrane 發表了第3 代，幾乎是全部都再進化，單體部份Marten 與Accuton 合作研發出新一代CELL 單體，擁有更完美的時間、相位一致，從高音、中音到低音單體都擁有一樣的聲學一致性，而且失真非常低，就算大音量下仍保持很低的失真。
Cell 高音為純鑽石打造，Cell 中音為純陶瓷，低音改採鋁三明治結構，尺寸比Coltrane 2的11″ 小一些，改為10″。oltrane 3 的一階分音線路與Coltrane Supreme 2 設計相同。箱體部份，前面板採用三明治結構，在兩層木板中間多了一層鋁板。在底座上，Coltrane 3 加大尺寸，而且用上易於調整高低的角錐設計。也因為單體的驅動系統更為強大，與箱體的結構進化，Coltrane 3 的重量增加到95Kg，效率約下降一些為88 dB，阻抗也略降低，6 ohm。

THE EVOLUTION OF COLTRANE
The Coltrane series began when lead designer, Leif Mårten Olofsson developed his first 3-way speaker. They were some of the first speaker models to employ a pure diamond tweeter combined with a carbon fibre cabinet, a combination that produced outstanding results.
2003 The first Coltrane model took Marten outside Scandinavia to reach a greater international audience
2006 The Coltrane Supreme established Marten as a leading name in high-end hi-fi
2014 The Coltrane Supreme 2 employed the new CELL drivers and a first order crossover to create unique time and phase coherence
2015 The Coltrane 3 takes the audio experience to the next level, combining the best Marten technology and design to date
