The result? Extreme clarity, speed and resolution, and uncannily musical even at low volume. Making the Coltrane series the ultimate reference in sound reproduction.
The new Master
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
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 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.
The units all employ the newly developed Cell drivers.
- One 20mm diamond tweeter
- One 51mm lower treble diamond tweeter
- One 5 ceramic mid range unit
- One 8 aluminium laminated sandwich mid-bass driver
- Six 8 aluminium laminated sandwich low-bass drivers
- Six 11 sandwich passive radiators with the bass lowest below 40Htz
CELL concept drivers
Our joint venture with Accuton represents a new milestone in hi-fi history. Accuton developed the unique CELL concept drivers used within the Coltrane Supreme 2. Tweeters, midrange and bass drivers have identical acoustic centres, delivering flawless phase and time coherency. The domes in the units are perfectly rigid, for impeccable signal settle and piston behaviour. And there is incredibly low distortion, in the magnitude of electronic devices, even at high levels.
- Steady decay of higher order harmonics
- High bandwidth.
All models have high-gloss carbon fibre sides with fronts available in:
