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.

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.

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.

Four finishes, each expressing the same design in a different material. True Grain Oak — new to Marten and exclusive to the Dexter series — retains the natural texture of the wood, tactile in a way that is particular to this finish. The matte veneers are hand-sanded and sealed. The piano finishes are built up through multiple lacquer layers and polished to depth.
