Our goal was simple. To design the best speaker in the world. With the Coltrane Supreme 2, we’ve arrived at where we want to be. Our ultimate design. To create the ultimate speaker, we needed an absolute reference point. We recorded our own album, ‘Supreme Sessions.’ The result? With eyes closed, the playback of the recording is identical to the live performance. The live feeling of the music, played by the musicians at the point of the recording, is reproduced in every detail.

Simply, the Coltrane Supreme 2 has a sound quality so genuine that distinguishing between recorded music and reality is not possible. High Fidelity in its essence. In fulfilling our dream of creating the best speaker in the world, no corners have been cut. No compromises made. Every single element is the best, period.


The sides are made of 27mm thick carbon fibre laminate, layered with 45mm 5-layered wood. The carbon fibre laminate is two layers of carbon sandwiched together with honeycomb Kevlar in between. The lever principle with these two layers, and the slight curve of the sides, makes these materials stronger yet, lending a ‘non-stretching’ effect. And making it one of the strongest materials in the world.

The wooden fronts and backs are made of four 70mm thick layers of solid wood and wood materials, sandwiched together with deadening glue. The lever principle applies here, too, making them exceptionally rigid.

The feet are of Marten’s own production and design, made of high quality stainless steel. BDR pucks and cones, made of solid carbon fibre, dampen any resonance remarkably effectively.


The binding posts and terminals are ‘WBT Next Gen’ and are made of minimized metal, providing extremely good signal properties. The internal wiring is the new Jorma Design Statement. These are custom-made with a specially designed steel shielding giving zero distortion between the cables. In total, we use 60 metres of this exceptional wiring. The crossover is an entirely new approach. This technique, based on the joint venture with Accuton and their CELL technology, creates a sound which is 100% time and phase coherent. This means that all the frequencies are rendered and outputted at the exact same moment. Very few loudspeakers are capable of this.
