Coltrane Supreme Extreme is the most advanced loudspeaker we have ever created. With its dual-tower and bespoke drivers, it delivers outstanding resolution and dynamic power. It features the largest beryllium midrange ever created, Crystalid mid-bass units, and a carbon fibre monocoque cabinet strengthened by solid wood and aluminium. Each pair takes over 800 hours to build, complete with Jorma Paragon cabling and custom Marten terminals. Shown as a static display, it offers a rare chance to see our most ambitious project ahead of its official launch later this year
We invite you to discover the next evolution of the Marten sound – uncompromising in approach, pure in expression, without limits.
