Overview

Crafted with meticulous attention to detail and a passion for sonic purity, Coltrane Quintet is a testament to their dedication to pushing the boundaries of what’s possible in high-fidelity audio. Featuring a 4-way bass reflex system, this speaker promises a captivating listening experience which sounds like no other.

Central to Coltrane Quintet’s exceptional performance are its custom-designed drivers, meticulously engineered to faithfully reproduce natural, detailed sound. From the delicate shimmer of the diamond tweeter to the nuanced detail of the beryllium high midrange, every component works in harmony to create a rich, dynamic soundstage.

One of the standout features of the speaker is the new custom convex carbon fibre mid-bass driver, which delivers controlled sound with remarkable precision. Combined with the aluminium sandwich bass drivers, the three custom drivers form the foundation of the Coltrane Quintet’s immersive sound.

To ensure seamless integration and coherence between the drivers, it features Marten’s signature first-order crossover—a cornerstone of our commitment to sonic purity and precision.

Beyond its performance, Quintet upholds the aesthetic principles that make a Marten speaker stand out. Housed in a newly developed cabinet, the polished carbon fibre is now visible, highlighting the strength of this essential Coltrane material. The fronts are available in a range of matte and piano gloss finishes.

Equipped with Jorma internal wiring and Marten Isolators, Coltrane Quintet ensures that every note is reproduced with clarity and realism, inviting listeners to immerse themselves in music that feels immediate, live and real.

If you have any questions about the new Coltrane Quintet or any of the Marten range we would love to hear from you.
