Dexter Quintet is the flagship of the series. A three-way design in which every driver is designed by Marten, built around technologies that began at the very top of our range — and a speaker that exceeded its own specification during development.

Three Drivers, Resolved as One Design

Three drivers, each designed by Marten, each working in its own range. Around them, every element — cabinet, crossover, bass loading — has been developed to the same standard. A triple-layer cabinet built to remove resonance from the equation. A crossover resolved individually for the drivers it serves. A bass loading system that delivers deep, controlled output with minimal distortion. The integration is the design.

The tweeter is diamond. Not as an option. Not as an upgrade. It was the starting point for every design decision that followed.

Isolators & Cabinet

The Speaker Disappears - The Music Does Not

Marten Isolators, developed with IsoAcoustics, substantially decouple the cabinet from the floor — reducing resonance transfer and opening the soundstage. The cabinet is M-Core triple-layer construction, with a carbon fibre laminate faceplate surrounding the tweeter and midrange.

Marten Dexter Quintet

The Marten Dexter Quintet is the flagship of the Dexter series and a 3-way floorstanding loudspeaker built around technologies developed at the top of Marten's range. It shares its driver architecture with the Dexter Quartet -- a pure diamond tweeter, a 3.5-inch ceramic midrange, and 9.5" carbon fibre bass drivers -- but extends the bass array to two drivers, increases cabinet depth, and applies the carbon fibre faceplate across both the tweeter and midrange positions. Marten states the Quintet exceeded its own specification during development. It is available in Standard and Statement Edition configurations, in four finishes, & is hand built in Mölndal, Sweden.

The Dexter Series

The Dexter series comprises four models: Dexter Duo, Dexter Trio, Dexter Quartet, and Dexter Quintet. All four share a common platform: the same pure diamond tweeter, M-Core triple-layer cabinet construction, Loaded Reflex Line bass loading, and Jorma Duality internal wiring. The Quintet and Quartet are the 3-way models, using a dedicated ceramic midrange and carbon fibre bass driver separate from the tweeter. The Quintet is distinguished from the Quartet by its twin bass drivers and the larger, deeper cabinet required to load them. Marten states that the Quartet was designed for rooms where the Quintet's proportions exceed what the space calls for.

Cabinet & Faceplate

The cabinet is M-Core triple-layer construction. The carbon fibre laminate faceplate surrounds both the tweeter and the midrange driver in the Quintet, an extension of the faceplate coverage compared to the Dexter Duo and Trio where the faceplate surrounds the tweeter only. Marten Isolators, developed with IsoAcoustics, decouple the cabinet from the floor to reduce resonance transfer.

Standard & Statement Edition

The Standard Edition uses Jorma Duality internal wiring throughout. The Statement Edition uses Jorma Statement internal wiring and highest-quality crossover components. Both versions share the same drivers, cabinet, bass loading, and overall design.
