Marten Dexter Duo Bookshelf Loudspeakers
Nothing between the listener and the music.
Technology earned, not borrowed.
Dexter Duo is a 2-way stand speaker and the entry point to the series — one that makes no concessions in the elements that matter most. The same diamond tweeter found in every Dexter model. The same M-Core cabinet. The same approach to bass loading. What changes is scale; the intent is constant.
The design
Diamond and ceramic, resolved as one design.
A diamond tweeter and a ceramic mid/bass driver, each designed by Marten. Around them, every element — cabinet, crossover, bass loading — developed to the same standard as the rest of the series. 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 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.
