Marten Coltrane Supreme 2 MK2 is the prestige model for the Coltrane Series. Marten wanted to create the ultimate speaker for the home – perhaps the best in the world. Designed using our recording studio in Sweden as reference, the difference between reality and recorded sound is indistinguishable.

The Coltrane series drives many of the design and technology innovations at Marten; Supreme 2 is no exception. It led breakthroughs in the Marten product range and continues to lead the market.

Marten developed a first order crossover for Supreme 2, creating absolute perfect time and phase coherence; and flawless time coincidence. A milestone for innovation and design at Marten. Your music is absolutely faithful, with a soundstage that is as vivid as the live performance. With Cell technology, the three-part cabinet includes a separate mid-cabinet of Corian, Stainless Steel and Aluminium, making Supreme 2 extremely strong and stable.

Pure Diamond is the ultimate material for speaker membranes. Used in the high-frequency range, its stiffness-to-weight ratio and internal sound velocity are unsurpassed. Diamond is also the best heat conductor known to man. This is essential for loudspeaker membranes, providing the best heatsink for the voice coil; resulting in high power handling and very low compression.

The sonic character of Marten Diamond tweeters is not what you might expect. Others can sound ‘overly brilliant’ or ‘hard-as-diamond’. Harmonic distortion can be a problem too. The Marten crossover has been carefully designed to deal with this. In fact, you get the opposite – the Diamonds simply disappear, leaving only your music.

Hard ceramic is light, yet extremely rigid, making it one of the best materials for speaker membranes – it’s also known as Sapphire. Marten ceramic domes have a high internal damping factor, because of a refined electrochemical process. The membrane also has a high material resonance frequency, meaning distortion is minimal; offering a level of clarity that is the holy grail for high end speaker domes.
