Marten Coltrane Supreme Extreme
The Marten Coltrane Supreme Extreme stands as one of the most ambitious loudspeakers ever created, a no compromise achievement in audio engineering and musical reproduction. It represents the absolute summit of high end design. Towering in scale yet refined in execution, each cabinet is constructed from multi layer carbon fibre sandwiching precision damped materials to eliminate resonance and colouration, ensuring only the purest signal remains. Inside, an array of custom built Accuton Cell drivers, including diamond tweeters, diamond midranges and ultra rigid ceramic woofers operate with astonishing speed, control and transparency, extending frequency response beyond the limits of human hearing. The crossover network, built with the world’s finest components, is engineered to achieve seamless phase coherence and time alignment, creating a soundstage of almost holographic realism. With dynamics that can shift effortlessly from the subtlest brush of a cymbal to the full force of a live orchestra, the Coltrane Supreme Extreme is more than a loudspeaker, it is the ultimate reference instrument for experiencing music in its most truthful, breathtaking form. Every detail, from the bespoke binding posts to the sculptural presence of the cabinets themselves, speaks to Marten’s relentless pursuit of perfection. For those who demand nothing less than the extraordinary, this is the endgame.
