Marten Coltrane Quintet Floor-standing Loudspeakers

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.

Coltrane Quintet features 2 x 10” aluminium sandwich drivers meticulously engineered for exemplary bass performance. These drivers excel in delivering deep, powerful bass with exceptional clarity and precision. The aluminium sandwich construction ensures optimal stiffness and damping, minimising distortion and resonance for a tight, articulate bass response.

These drivers ensure every note in the lower ranges are reproduced with stunning detail and impact, allowing you to really feel the music.

Using carbon fibre for Coltrane Quintet’s cabinets is an easy choice, due to its superior technological advantages and profound impact on sound quality. Its rigidity and low resonance minimise cabinet vibrations, ensuring the drivers operate with maximum accuracy. This results in transparent and natural sound reproduction, capturing every detail of the music.

Available in lacquered Piano Black carbon fibre for high gloss, minimalist style.

The Coltrane Quintet baffle can be constructed from solid wood or high-gloss lacquered fiberboard—both layered with aluminum for stability and resonance reduction.

Opt for, carefully selected walnut or oak to give you a warm, natural finish, or for those more bold among us, there are five contemporary gloss finishes: Piano Black, Piano Grey, Piano Plum, Piano Red and Piano Gold.

We take every detail seriously to ensure the best possible listening experience. That’s why we use Jorma internal wiring, which are handmade in Sweden to the highest standards of quality and performance. Using separate + and – conductors, Jorma cables offer enhanced shielding and the highest quality copper, resulting in a natural, transparent sound that perfectly complements our speaker design. Jorma delivers exactly what we need to achieve the best possible sound.

Reducing resonance is crucial to the design of our speakers as it can significantly impact the sound quality. That’s why we developed Marten Isolators with IsoAcoustics technology. These precision isolators separate the cabinet from the floor, reducing resonance and distortion—freeing the soundstage.

Coltrane Quintet can be upgraded to Statement Edition, featuring Jorma Statement internal cables and the highest quality crossover components.

The first order crossover has always been an integral component of the Coltrane sound. The crossover for Coltrane Quintet offers sound which is open, clean and dynamic, making it exceptionally powerful in the bass frequencies. This type of crossover makes it possible to have perfect time and phase coherence; and flawless time coincidence. This means that all registers are generated at the exact same moment, as it was recorded.

We use only the finest components for our crossovers:

• Copper foil air core coils
• Silver/Copper in oil/paper capacitors
• Silver/Gold capacitors
• Custom-made resistors
• Jorma internal wiring
