Coltrane Supreme Extreme is our no-limits flagship: a five-way, dual-tower speaker built to redefine what’s possible in home audio. At its side is Coltrane Quintet Extreme using a 1” pure diamond tweeter, 3” diamond high midrange & 7” beryllium midrange.
Coltrane Supreme Extreme was created without limits—a five-way, dual-tower speaker built to push the boundaries of what’s possible. Coltrane Quintet Extreme distils that technology into a single-cabinet, four-way design. Both use first-order crossovers, Jorma Paragon internal wiring and Marten Isolators to preserve fidelity. One the pinnacle of our craft. The other, its closest companion.
Precision, redefined
Shared across both models are our finest custom drivers. The 1” and 3” diamond tweeters offer unmatched clarity and speed, while the 7” beryllium midrange delivers astonishing resolution with warmth and presence. With aluminium sandwich bass drivers and hand-built crossover components, these systems are voiced to reveal music in its most natural form.
Resonance, Resolved
Coltrane Supreme Extreme’s cabinet uses a seamless carbon fibre monocoque structure, combined with solid wood and aluminium layers for unmatched rigidity. Coltrane Quintet Extreme echoes this with a multi-layer carbon fibre laminate and the same structural front baffle design. Every element is engineered to eliminate resonance—so only the performance remains.
Supreme Extreme and Quintet Extreme are available in a carefully chosen palette of finishes, each hand-applied for a flawless result. Whether in natural wood or rich lacquer, the finish complements the form—creating a speaker that speaks as clearly to the eye as it does to the ear.
