Coltrane Quintet’s pure diamond tweeter offers the best in sound reproduction, leveraging diamond’s unique properties for unrivalled clarity and precision.

With its exceptional stiffness-to-weight ratio, pure diamond ensures instantaneous response without distortion, revealing intricate details with accuracy. Additionally, diamond’s thermal conductivity guarantees stable performance even under intense listening conditions, preserving the tweeter’s integrity and longevity.

Integrating this tweeter into Coltrane Quintet offers an immersive, lifelike listening experience that sets an enviable standard in high-end audio reproduction.

Our pure beryllium high-midrange driver epitomises our pursuit of sonic perfection. Tailored with precision, it harnesses beryllium’s exceptional properties for performance. Its stiffness, lightness, and damping ensure accurate reproduction of vocals and instruments with precision.

The driver’s fast transient response captures every nuance of the original recording, while its seamless integration with our signature first-order crossover ensures coherence across frequencies. In Coltrane Quintet, this driver delivers unmatched clarity, detail, and musicality: bringing music to life.

The convex carbon fibre mid-bass driver offers a host of benefits to offer Coltrane Quintet. Its convex shape enhances rigidity while minimising weight, allowing for greater piston-like motion and improved transient response. This translates into tighter, more articulate bass reproduction with remarkable speed and accuracy, ensuring every note is delivered with precision and impact.

Furthermore, the use of carbon fibre provides exceptional damping properties, reducing unwanted resonance and distortion for a cleaner, more transparent sound. This means you can enjoy controlled, powerful bass without any muddiness, even at high volumes.
